Profligacy / jruby gem question

Dear all,

I’ve been trying to install the profligacy gem
(http://ihate.rubyforge.org/profligacy/sample.html) in Jruby,
but couldn’t use it (in ubuntu 8.04).

With the gems version, I get this error:

/usr/local/jruby-1.1.3/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
require': no such file to load -- profligacy/swing (LoadError) from /usr/local/jruby-1.1.3/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in require’
from prof01.rb:3

With the *gz version, I get this error:

axel@alecrim:~$ jruby prof01.rb
prof01.rb:2:in `require’: no such file to load – profligacy/swing
(LoadError)
from prof01.rb:2

Is there a special path variable I have to name for Jruby gems ?

Thank you very much,

Best regards,

Axel
