rake is using default ruby on Mountain Lion

[pencilcheck]

I am using ruby from homebrew, but during the task, it says there is no xcodeproj gem from system built ruby gem; however, I have prepand /usr/local/bin at the beginning of my PATH. Is there a way to use homebrew ruby from the correct path instead of the system ruby?

I don't know how to rake this project.

My computer show this error.

I fix the error.

Change bin/build-exports.rb to your local ruby and gem path.

saimatoMacBook-Pro:mobiruby-ios cuizheng$ cat bin/build-exports.rb

#!/Users/cuizheng/.rvm/rubies/ruby-1.9.3-p194/bin/ruby

ENV['GEM_HOME'] = ENV['GEM_PATH'] = "/Users/cuizheng/.rvm/gems/ruby-1.9.3-p194"
