[ruby-it] How to use more than one gem version in the same application

[Paolo Montrasio]

I don't think it's feasible but as you wrote your question in English 
you probably wanted to post your question to the general Ruby forum at 
http://www.ruby-forum.com/forum/4 and not to the Italian one at 
http://www.ruby-forum.com/forum/19
You'll also find more people to advise you there.

Paolo
