It's taken a while of fighting though various blog posts to get to a mac with a stable Textmate, RVM, two versions of Ruby (1.8.7, 1.9.2) and two versions of Rails (2.3.8 and 3.0.x).
Without further ado, here are the hard steps I've worked through to get it all working:
use .rvmrc to set your projects to the right ruby/gemset (create a gemset as well):
cd myproject rvm 1.9.2@myproject
Build textmate wrapper following the rvm instructions, then replace contents of textmate_ruby file:
#!/usr/bin/env sh source ~/.rvm/scripts/rvm cd . exec ruby "$@"
Update this to a very recent version. (from github)
Also set RUBYOPT to rubygems in Shell Variables under the Advanced tab in TextMate setttings.
gem install rspec-rails
Follow instructions here:
Plist fix for textmate
Shut down textmate:
Make sure you are using ruby 1.9.2
rvm use 1.9.2

The Ruby on Rails bundle will need to be reinstalled as well to avoid the following error
