Getting this build system to work can be tricky. 

As I recall:

1. Install MSys.
2. Install MinGW where MSys expects it. You should install the gcc-core, gcc-g++, mingw-runtime, w31api, mingw32-make, and binutils packages. All of these appear to be necessary to get close to a Posix type build system.
3. If necessary, modify custom.py to point to /usr/local/include and /usr/local lib using, however, the complete WINDOWS (not MSys/Posix) pathnames.

See http://www.mingw.org/MinGWiki/index.php/Install%20MinGW for more information. This appears to be reasonably current.

Hope this helps,
Mike
