Textmate bundle can't find Cake gem?

[Stu]

Hi,

[This is a question I asked first on the Cake mailing list to see if
this was a Cake rather than Clojure bundle issue].

I've successfully (I hope) installed Cake via Ruby gems, all based on
an RVM installation on OS/X. The various commands seem to work and the
REPL seems to behave as I expected. The Ruby and other bundles find
the RVM gems as needed too. Nice!

Next step was to install the TextMate Clojure bundle (https://
github.com/swannodette/textmate-clojure) and try that out. I found I
needed to add the directory containing the cake bin to the TM_PATH
environment variable for the bundle to find Cake.

A command-R in a Clojure file reports that Cake has been started, but
a file load or form eval always yields:

/Users/foo/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/
rubygems.rb:899:in `report_activate_error': Could not find RubyGem
cake (>= 0) (Gem::LoadError) from /Users/foo/.rvm/rubies/ruby-1.9.2-
p180/lib/ruby/site_ruby/1.9.1/rubygems.rb:248:in `activate' from /
Users/foo/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/
rubygems.rb:1275:in `gem' from /Users/foo/.rvm/gems/ruby-1.9.2-p180/
bin/cake:18:in `'

Can anyone else using OS/X+RVM+Cake advise on the best way to go about
this?

Thanks!
