trying to debug another issue I had on 10.6 with git-tmbundle, I decided to run the specs. I get an error:

... in the git.tmbundle $ cd Support/spec/ $ ruby run_all_spec.rb

./controllers/../../tmvc/lib/ruby_tm_helpers.rb:5:in `require': no such file to load -- /lib/escape   (LoadError)
    from ./controllers/../../tmvc/lib/ruby_tm_helpers.rb:5
    from ./controllers/../../tmvc/tmvc.rb:10:in `require'
    from ./controllers/../../tmvc/tmvc.rb:10
    from ./controllers/../../tmvc/tmvc.rb:9:in `each'
    from ./controllers/../../tmvc/tmvc.rb:9
    from ./controllers/../../environment.rb:1:in `require'
    from ./controllers/../../environment.rb:1
    from ./controllers/../spec_helper.rb:3:in `require'
    from ./controllers/../spec_helper.rb:3
    from ./controllers/annotate_controller_spec.rb:1:in `require'

    from run_all_spec.rb:2
    from run_all_spec.rb:1:in `each'

This is using the latest cutting edge TextMate version too.
