I'm using Windows 7 x64 SP1. I am using the most recent RubyInstaller
(2.0.0-p247 x64) and DevKit (DevKit-mingw64-64-4.7.2-2013022-1432-sfx).

That's disappointing to hear that most folks use Ruby exclusively in *nix
environments. That really limits its utility for me. I am trying Ruby
because dealing with HTTP in Java is a huge pain, and I was having
difficulties setting up a Python environment in Windows, too (go figure).

DevKit is a MingW/MSYS wrapper for Windows Ruby development.  It might not
be finding it, but he does have a C dev environment.

I know you cut them out earlier, but would you mind sending some of the C
Header Blather our way?  It's probably got some clues as to what's going
on.

Also - which versions of Windows, RubyInstaller, and DevKit are you using?
