CPAN not working, or is it?

[Gary Stainburn]

I'm replacing a dead F19 box with a new C7 one and I'm trying to get my Perl
install completed. Ultimately, I need to get Selenium::Remote::Driver
working, but I'm struggling before that.

I started off as always by using RPM's for everything I possibly can. I then
started to use CPAN for everything else. It looked like CPAN was working and
things were installing "OK".

However, as I went for bigger modules, anything that had dependences were
then failing as the dependencie were installed OK but then did not appear to
be available.

The last thing I've just tried is to update CPAN as the RPM is 1.9800 and the
latest is 2.6. As you can see below, the install worked, but when it
reloaded, or when I came out and went back in, it still showed 1.9800

Anyone got any ideas what I need to do?

I doubt this old post will help you any:

What often happens when you have "larger" modules, they reply on libraries.  To build the perl module from source, you need to devel rpm of the library installed to link against.

example
libxml2-2.7.6-21.el6_8.1.x86_64
libxml2-devel-2.7.6-21.el6_8.1.x86_64

XML::Simple won't build unless the devel is present

CPAN isn't real good at reporting why the build failed, just that it failed.

What I've learned to  do when I have this sort of issue is to pop out of CPAN and into ~/.cpan/build.

Locate the unpacked module and try the build manually.

I get better errors that way.
