Ruby gem , require and version problem

Ruby

Hi,

I am trying to specify the version a gem, which is installed in two
versions under slightly different names as a result of forked projects
which we now intend to merge back.

Looks like this in ‘gem list’
ruby-foo-bar (0.9.2)
foo-bar (0.9)

Both are supposedly required with:
require ‘bar’

Now, I need to specifiy which of the two to use for my script - and I
started with

require ‘rubygems’
gem ‘bar’, ‘0.9.2’

Throws an error
/usr/lib/ruby/1.8/rubygems.rb:827:in `report_activate_error’: Could not
find RubyGem bar (= 0.9.2) (Gem::LoadError)

Ok, so then I tried specifiying the names as they appear in the ‘gem
list’

require ‘rubygems’
gem ‘ruby-foo-bar’, ‘0.9.2’

That doesn’t throw an error, but the game is apparently not loaded as
the modules and classes are not recognized subsequently.

System is a fairly fresh install of Ubuntu 9.19, 64 bit and ruby 1.8.7,
rubygems version is 1.3.5

Any advice would be appreciated.

gem doesn’t load any files, it just activates the right gem.

require ‘rubygems’
gem ‘ruby-foo-bar’, ‘0.9.2’
require ‘bar’
