Hi -

I'm excited about the macruby project. I just started playing with it. It's a great tool to get to know the frameworks on OS X.

I created a quick script that imports all frameworks in /System/Library/Frameworks - however, it fails on some of the frameworks. I'm not sure what exactly is going on. Here is some sample code:

frameworks = `ls /System/Library/Frameworks/`
frameworks.chomp!
frameworks = frameworks.split
frameworks.each do |f|
  f.gsub!('.framework', '')
end
frameworks.each do |f|
   framework f
end

It dies with this error:

Any idea what is going on?

Thanks in advance for any help.
