Hmm, this error really only happens when you secretly/accidently use a
64bit Python version after all. Make absolutely sure your Python is
32bit. From the build paths you cannot tell, because you have overriden
those in a user-config.py/custom config. Also, if you use the same build
paths for 32bit and 64bit, it is probably a good idea to run a scons
with clean target after all. Even better is to use custom configurations
for different bitnesses.

I use two different configurations, called graphicall_32b and
graphicall_64, both pointing to different BF_BUILDDIR and BF_INSTALLDIR.
I activate them on command-line by passing them to scons with
BF_CONFIG=graphicall_32b and BF_CONFIG=graphicall_64b respectively.

This works, I build many times a day 32bit versions of Blender on my
64bit Win7 Ultimate.
