Subject: Re: XCode, Mac OS X, Ruby C Extension

Hi,

The Xcode template will produce an extension that may only work for
the version of Ruby that ships with the system. I don't know why it
doesn't work with the version in MacPorts, could you provide more
feedback about this (like a backtrace)? Maybe it's because the
extension is built 2-way fat (for i386 and ppc) by default.

Anyway if you want to write an extension that should be portable with
different versions of Ruby, as others suggested you should use mkmf.
