gems in $HOME

[Matthieu Imbert <matthieu.imbert@ens-lyon.fr>]

Hi,

I'm new to ruby and rubygems. I installed the debian rubygems package 
(from debian testing) and I'm trying to configure it to have gems in my 
$HOME dir as this is a shared server.

For this I tried several things:

- setting in environment:

  export RUBYOPT=-rubygems
  export RUBYLIB=$HOME/.gem_home
  export PATH=$HOME/.gem_home/bin:$PATH
  export GEM_HOME=$HOME/.gem_home

- same thing except setting gem_home: /home/username/.gem_home in 
~/.gemrc instead of environment

- after having read http://docs.rubygems.org/read/chapter/15#page101 I 
also tried different path combinations, like:

  in ~/.gemrc:

    gemhome: /home/username/.gem/lib/ruby/gems/1.8
    gempath:
     - /home/username/.gem/lib/ruby/gems/1.8
     - /var/lib/gems

  in environment:

    export RUBYOPT=-rubygems
    export RUBYLIB=$HOME/.gem/lib/ruby:$HOME/.gem/lib/site-ruby/1.8
    export PATH=$HOME/.gem/lib/ruby/gems/1.8/bin

Unfortunately, in all cases, I can't get it to work. For example, I 
install a package:

gem install capistrano

Installation seems ok, but when i run the cap command (part of 
capistrano) I always get:

$ cap
/usr/lib/ruby/vendor_ruby/1.8/rubygems/dependency.rb:247:in `to_specs': 
Could not find capistrano (>= 0) amongst [] (Gem::LoadError)
	from /usr/lib/ruby/vendor_ruby/1.8/rubygems/dependency.rb:256:in `to_spec'
	from /usr/lib/ruby/vendor_ruby/1.8/rubygems.rb:1208:in `gem'
	from /home/mimbert/.gem/lib/ruby/gems/1.8/bin/cap:18

Can someone help me solving this issue? Sorry if I post to the wrong 
mailing list, but it seems to me that this would be the best place for 
help on this issue.
