It is not possible to install cpanm from cpanmin.us

[C. L. Martinez]

Hi all,

I am trying to do a fresh install in a CentOS 6.4 server, but cpanm
can not be installed.
Somebody knows how can I fix this error??

Not sure why you're getting those errors.  The root error seems to be:

! Installing version failed. See
/root/.cpanm/work/1377081249.11700/build.log for details. Retry with
--force to force install it.
! Installing the dependencies failed: Installed version (0.77) of

Can you try installing App::cpanminus using the built-in cpan utility?  If you're on Debian/Ubuntu, you can apt-get install cpanminus

It is a centos host. I can to try install via epel Repo.

[C. L. Martinez]

Uhmm ... The problem is more serious: you cannot install any of the
perl modules using this command to install cpanm "curl --insecure -L
http://cpanmin.us | perl - App::cpanminus" that ELSA requires under
RHEL6.x platforms (tested on CentOS 6.4, OEL 6.4 and RedHat 6.4) ....

The only option is to install cpanm using "curl -LO
http://xrl.us/cpanm". After that, you need to install these packages:
perl-CPAN and perl-Test-Simple from official repos. If these packages
are not installed prior to installing any cpan module, all cpan
modules fail in its installation (for node and web components).

Due to the change introduced some time ago in which web node needs to
be installed in the same host as ELSA node, under
"centos_get_web_packages" section, it is needed to remove
perl-Module-Build, perl-Module-Install and perl-libwww-perl packages
because they are installed previously by "build_node_perl" section ...

Another point: under RHEL-like distros, it is not need to install
Net::OpenSSH module using "-n" switch, works ok without it.

And last: Martin, Is it needed to install Test-Pod module using "cpanm
http://search.cpan.org/CPAN/authors/id/D/DW/DWHEELER/Test-Pod-1.46.tar.gz"??
It is installed without problems as a dependency during the rest of
web node modules, but with release 1.48.


Remember, all these comments are only for RHEL based distros ... I
don't know if it is applicable to ubuntu, freebsd, etc ...

P.D: This procedure is tested for new installations with r1008 release only

[Martin Holste]

I will do some testing on this today and get to the bottom of the issue.  Thanks for reporting it!

[Martin Holste]

Ok, I've changed install.sh for CentOS to install a few other modules via yum before attempting to install cpanm.  Please let me know if this works for you now.

Searching in http://www.cpan.org/authors/id/M/MI/MIYAGAWA, version
1.6942 it doesn't exists ....

Martin, could be possible to use "freeze" versions for perl modules as
does Qradar, ArcSight, etc ??? This could prevent many installation
problems and incompatibilities ...

I will continue the test but using cpanm binary from http://xrl.us ...

Ok, all is working now under CentOS 6.4 x86_64 and using cpanm binary
provided bt http://xrl.us ...

lol, too funny. i've been fighting with something similar in CIF last few days. #irony

and google searches lead me to YOU wonderful people! ;)

my guess is that it has something to do with:

I'm going to be working on using Perl's Carton module to set static Perl module versions in the near future.  It's a terrific module by my hero Miyagawa that authored many of the most important Perl modules that ELSA uses, such as Plack and cpanm.  Even better, I'm going to be working on having a stable and dev branch for ELSA versions, which will be important with the upcoming major refactor.

neato.

it seems as if the thing here is (and i've seen this in the past with CIF and RHEL), it ends up being RHEL release engineers making certain assumptions about things, and then perl authors making other assumptions that clash...

usually it's fairly easy to work-around, but sometimes they are low level enough to make you want to scream. i've considered trying to package as many of the libs into a package to make things stable, but then you run into other lower level issues that rely on XS (TLS, INET, etc) where the underlying distro/arch comes into play...

not impossible, but also why we're gonna move some of the lower level stuff to C in the future and reduce some of the complexity that comes with the higher level languages (different set of problems, but reducing complexity seems to always help at some level...).

i'm starting to notice this as a trend as "it becomes easier to build applications rapidly a-top of things like perl", interesting to see this (and other) ways authors are starting to identify and work-around the problem (something unique to the open-source space).

this topic should be interesting moving forward. if you do stuff like you're suggesting, i'd be interested in how it works out for you (maybe we can work together on a community doc or something, lower the barrier for other security devs in this space).

cheers,
