If you install stuff as eggs, some of them may always be imported on 
Python startup. (I guess this is so for namespace hook-ful packages.)

Do you mean that if you start from scratch, and install only the numpy
+scipy packages you built for 64-bit Windows, all problems apart from the 
MKL ones disappear?

Do the other packages you had installed use the same C runtime as the 
ones you built, and were they compiled with the same compilers?
