Note that binary gems don't work only because they install their
binary aspect into the wrong directory (and, if you have the newer
versions of rubygems, auto-install a version which doesn't exist so
you'd need to specify you want the win32 gem).  Once you install it
you can easily copy the .so's to the right directory and they will
'probably' work just fine.

Note that mongrel works if you do this then just go into mongrel.rb
and change their 'win32' regexes to be win32|mingw

Good luck!
