Non standard installed gem question

Bonjour à tous,

I’m trying to install and use one particular gem in a non-standard
location.
I’d like to keep using both standard or non-standard installed gems.

I’v been able to install the “rgl” (Ruby Graph Library) in a personnal
directory
like this :

export MY_GEMS=/home/.../pack/ruby/gems/1.8/
gem install rgl -i $MY_GEMS -t --debug

But I’m unable to use it :

export GEM_PATH=$MY_GEMS

irb
>require "rubygems"
>gem "rgl"

gem “rgl”
Gem::LoadError: Could not find RubyGem rgl (>= 0.0.0)

from /opt/local/lib/ruby/vendor_ruby/1.8/rubygems.rb:304:in
report_activate_error' from /opt/local/lib/ruby/vendor_ruby/1.8/rubygems.rb:238:inactivate’
from /opt/local/lib/ruby/vendor_ruby/1.8/rubygems.rb:76:in
active_gem_with_options' from /opt/local/lib/ruby/vendor_ruby/1.8/rubygems.rb:50:ingem’
from (irb):3

Thank you for any help

I cannot reproduce:

$ rm -rf ~/tmp/gems/
$ export MY_GEMS=~/tmp/gems
$ gem install rgl -i $MY_GEMS -t
[…]
3 gems installed
[…]
$ export GEM_PATH=$MY_GEMS
$ irb
irb(main):001:0> require ‘rubygems’
=> true
irb(main):002:0> gem ‘rgl’
=> true
irb(main):003:0> Gem.path
=> ["/Users/drbrain/tmp/gems", “/Library/Ruby/Gems/1.8”]

Check to see if irb is looking in the right spot ^^

Hum, I also success thank’s to your commands (perhaps I’ve done some
mistake
with my numerous trys, with several ruby versions (macport et apple)
and the various gems repositories I tested…)
But now I sure this was the way to go!

rm -rf ~/tmp/gems/1.8
export MY_GEMS=~/tmp/gems/1.8
gem install rgl -i $MY_GEMS --no-rdoc --no-ri -y

(faster without docs)

export GEM_PATH=$MY_GEMS

irb

require ‘rubygems’

generaly return false !?

gem ‘rgl’

=> true

Gem.path

=> ["/Users/diam/tmp/gems/1.8", “/opt/local/lib/ruby/gems/1.8”]

Thank your very much for your fast help!
