Gem installed incorrectly on Mountain Lion 10.8.2

[dodikk]

The gem has been installed to the system ruby directory

/Library/Ruby/Gems/1.8/gems/motion-testflight-1.4/lib/motion/project/testflight.rb

---

Instead of the RubyMotion directory

/Library/RubyMotion/lib/motion/project/testflight.rb

[dodikk]

It used to produce an error below :

dodikk$ rake testflight notes='First test build'
(in /Users/dodikk/projects/ruby/RubyMotionTestApp)
rake aborted!
no such file to load -- motion-testflight
