Comment:

 Hi thanks for reporting the problem you had. You might want to ask your
 questions directly to the mailing list but here is a quick overview of the
 current situation (macruby 0.4).

 macgem doesn't work properly and won't install your gems. C extensions are
 not supported. MacRuby can't compile iPhone apps written in Ruby.
 If you want to use pure Ruby libraries unpack the libraries in your
 project and load them manually.

 - Matt

 Replying to [ticket:243 leebutterman@…]:
...
I just downloaded MacRuby 0.4 on OS 10.5.6, launched the bundle, opened
 up a terminal, tried to install a few packages, and my CPUs revved up to
 150%, and segfaulted.
My ultimate goal in using MacRuby is to make an iPhone app in Ruby, not
 Objective-C.  When, if ever, would this be an acceptable and recommended
 use of MacRuby?
