[MacRuby-devel] Fwd: How do I get gems into XCode/MacRuby environment?

Okay, one elegant way to do make gems visible to MacRuby in XCode4 is to add environment variables GEM_HOME and GEM_PATH in the "Scheme".
If you have ruby 1.9.2 installed via rvm (rvm.beginrescueend.com) as I do, type:
>rvm 1.9.2
>rvm info
Look for the GEM_HOME and GEM_PATH values, and add these into the Environment Variables table in the Arguments tab of the XCode/Scheme/Edit Scheme dialog (whew!).
Then just install whatever gems you need at the command line within rvm.
