The RubyObjC source code is hosted on RubyForge and is available for download.

Here are the instructions for downloading RubyObjC.

Once you’ve obtained the RubyObjC sources, you can rebuild RubyObjC by typing “rake” in the top level directory.

Then to build the gem, type “rake gem”.

“rake test” will run the RubyObjC regressions.

To install RubyObjC as a gem, use “sudo rake install”.
