First I downloaded Ruby 1.9.2 from RVM and I modified my path in .profile as follows:
PATH=$PATH:.:~/.rvm/rubies/ruby-1.9.2-p290
export PATH
Could that be the reason I'm having problems?

This won't affect TM, which keeps its own PATH variable rather than sourcing it from your profile: http://wiki.macromates.com/Troubleshooting/TextMateAndThePath.

I've changed a few things in my set up, though, so that might be the reason (?).

Did you modify TM's PATH variable in Preferences > Advanced > Shell Variables?

I've always been able to run Ruby programs from within Txmate, now I can't.

Is the problem that TM can't locate your Ruby executable? If the PATH isn't your problem, please provide the error message you're getting.

Best,
