Mechanize failure
Alex Young
Does anybody recognise this?
$ gem check -t mechanize
ERROR: While executing gem ... (NameError)
method `use_ssl?' not defined in Net::HTTP
This is on a Debian system, so I've probably forgotten an apt-get
install somewhere, but I can't spot which one:
$ dpkg -l | grep ruby
ii libmysql-ruby1 2.4.5-6.1 MySQL module for Ruby 1.8
ii libopenssl-rub 1.0.0+ruby1.8. OpenSSL interface for Ruby
ii libruby1.8 1.8.2-7sarge5 Libraries necessary to run Ruby 1.8
ii rdoc 1.8.2-1 Generate documentation from ruby

ii ruby 1.8.2-1 An interpreter of object-oriented

ii ruby1.8 1.8.2-7sarge5 Interpreter of object-oriented

You're cut off there for some reason, but you should make sure you have
libopenssl-ruby1.8 installed, not just libopenssl-ruby.

you'd want one rather than the other?

Compare:
apt-cache policy libopenssl-ruby
apt-cache policy libopenssl-ruby1.8
It looks like libopenssl-ruby is targeted at ruby 1.8.2.

Well, it was a thought. Trying it on my Debian box, I find that I can
install mechanize and it seems to work okay, but sudo gem check -t
mechanize produces:

..so at least I get a different error. It's possible that there is some
assumption about where I have RubyGems installed (/usr/local) that's
causing a problem. Here's my system:
% dpkg -l '*ruby*' | grep ii

Just for information, debian packages work this way: for each ruby
thing packaged for debian, there are (at least) two packages a
lib...-ruby and a lib...ruby1.8. The former is empty and depends on the
latter and is there to make the transition to newer versions of ruby
more easy (for the maintainers). packagers can also choose to provide a
-ruby1.9 version. (this is not true for all packages, but for the
greatest majority).

Wrong!
libopenssl-ruby is simply a dummy package designed to install the
appropriate version of the package for the appropriate version of the
interpreter. By installing ruby, you get ruby 1.8 pulled in as a dependancy
(as opposed to ruby 1.9). Likewise, by installing libopenssl-ruby, you get
libopenssl-ruby1.8 as opposed to 1.9. One day when 2.0 becomes the new
stable, you'll be upgraded to ruby2.0 and libopenssl-ruby2.0 automatically
because they'll be the new dependancies for the dummy package.
Package: libopenssl-ruby
[snip part of the description]
Description: OpenSSL interface for Ruby
This package makes Ruby to be able to use OpenSSL. It includes HTTP and
TELNET protocols' SSL/TLS support.
.
This package is a dependency package, which depends on Debian's default
Ruby version (currently 1.8.x).
