Грабли не могут быть найдены

эй я играл вокруг с bundler и некоторые драгоценные камни и теперь я не могу использовать rake больше

если я делаю простой db:migrate, я получаю эту ошибку:

mac:app antpaw$ rake db:migrate
/usr/local/lib/ruby/site_ruby/1.9.1/rubygems.rb:335:in `bin_path': can't find executable rake for rake-0.8.7 (Gem::Exception)
 from <internal:gem_prelude>:282:in `method_missing'
 from /usr/local/bin/rake:19:in `<main>'

но грабли перечислены, если я делаю gem list. Я использую направляющие 3.0.0beta4, bundler 1.0.0.beta.5, и рубин 1.9.2dev.

РЕДАКТИРОВАНИЕ, отправленное мой export

mac:trickpipe antpaw$ which ruby
/usr/local/bin/ruby
mac:trickpipe antpaw$ ruby -v
ruby 1.9.2dev (2010-07-02 revision 28524) [x86_64-darwin10.2.0]

Хорошо я испытал его, посмотрите, как сообщение об ошибке изменяется:

mac:trickpipe antpaw$ export GEM_HOME="/usr/local/lib/ruby/gems"

теперь с rvm:
