To refresh my dusted memory, I grepped the distutils dir for python2.7:

            """Python was built with Visual Studio 2008;
extensions must be built with a compiler than can generate compatible binaries.
Visual Studio 2008 was not found on this system. If you have Cygwin installed,
you can try compiling with MingW32, by passing "-c mingw32" to setup.py.""")

The same warning exist for Visual Studio 2003.

I also vaguely recall being able to put this flag into some dot file to
avoid modifying the setup.py invocations (but it's so vague I wonder if
it was for perl instead...).

Hth,
