Has anyone else had problems with the ruby 1.9.1 development headers on
OS X?

$ echo '#include "ruby.h"' >main.c
$ gcc -c main.c
In file included from /Users/jeff/usr/include/ruby/ruby.h:1125,
from /Users/jeff/usr/include/ruby.h:32,
from main.c:1:
/Users/jeff/usr/include/ruby/missing.h:35: error: redefinition of
?struct timespec?

You need to add -I option for platform specific headers, maybe
-I $HOME/usr/include/`uname -m`-darwin`uname -r`. mkmf.rb
should deal with it.

Apple has added a strange hack to gcc in their port so it reads
ruby/missing.h from
/System/Library/Frameworks/ruby.framework/Headers/config.h.
