If I give Bundle install I get
Gem::InstallError: factory_girl requires Ruby version >= 1.9.2.
But if I do ruby -v I get
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.2.0]
So the problem should be in rails or in bundle that uses the previous version of it, how can I fix it?
I solved reinstalling Ruby from source code and compiling!
