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!
