IIRC Python 2.5.x's distutils do not support MSVC 2008 of any kind, just
2003 and 2005. Python 2.6 (now in rc status) does support it.

Maybe :)
According to
http://msdn.microsoft.com/en-us/library/aa385638(VS.85).aspx mc.exe is
the message compiler, which might or might be not required to build DLLs
on Windows. It might be that the Express edition of 2008 does not
include it, but I do not have a MSVC 2008 professional handy at this
moment, but I can likely check later.

This is probably due to 2008 not being supported by Python 2.5. Some
people out there have patches for MSVC 2008 and Python 2.5.2, but you
have to Google for them since I did not bookmark those when I last came
across them. I have not looked at pyconfig.h, so I might be completely
wrong here.
Did you build Python yourself or did you use an installer? If you used a
binary build with MSVC 2005 I would not be surprised that even after
building the extension it might still blow up on loading due to ABI
breakage.
