Interesting - what does your compilation command look like?

I think I have tried the 'fixrbconfig' trick in the past in order to
install Rails, but I tried it again anyway and it didn't help. So
instead, I tried clearing out the OSX install of Ruby and installing
1.8.4 from ruby-lang.org (and then reinstalling narray in the new
location). I can get the extension to compile now, but when I try to
use it, I get the
following error:
