Textmate RSpec Run Example fails

When I try to run an RSpec example from within Textmate. I get "Rails requires RubyGems >= 1.3.2 (you have 1.3.1). Please gem update --system and try again." I run gem update and I get nothing to update. I think the RSpec bundle is running from the built in directories rather than /local/. How do I change wh开发者_StackOverflow社区ere the bundle looks?

Thanks! :)

So far the only solution that works is to install the new rails bundle. This has not proved to be a permanent fix as I had to remove and reinstall the bundle after a reboot. It also seems to only work with the rails bundle as I just installed the compass and blueprint bundle just after the reboot.

Hopefully a smart person can id a permanent fix

Thanks!
