[MacRuby-devel] framework cannot be loaded

[Laurent Sansonetti]

Hi Eric,

MacRuby requires Objective-C garbage collection because it actually  
uses it instead of the traditional Ruby collector. Check out the last  
point of http://ruby.macosforge.org/trac/wiki/WhyMacRuby for some more  
details.

Regards,
Laurent
