rdiscount is broken in os x snow leopard

[jurisgalang]

After installing via gems: gem install rdiscount
Invoking: rdiscount
Will yield:

ruby/18/gems/rdiscount-1.3.5/lib/rdiscount.bundle: dlopen(/.gem/ruby/18/gems/rdiscount-1.3.5/lib/rdiscount.bundle, 9): no suitable image found.

That probably doesn't actually fix it. require 'rdiscount' brings in the ruby lib, require 'rdiscount.so' brings in the C extension. Changing it to 'rdiscount' is probably just causing the extension not to load at all.

Reinstalling XCode from the Snow Leopard DVD fixed my ruby install, it was missing header files, etc...

After the reinstall I was able to successfully install rdiscount via gem.

Cool.
