I am not sure which numpy.distutils version you have (I am using the
one form git repo) and indeed the versions should match when I read
the code. So, try to fix the intel.py script so that it will
successfully find either intelem or intelvem. You can run the
intel.py script directly, just fix one line at the end of
the script to

   compiler = new_fcompiler(compiler='intelem')

for instance.

Another note: so you have both 32 and 64 bit versions of intel
compilers installed in the system. Perhaps numpy.distutils finds
32-bit ifort program first in the PATH variable and hence
it never can try the 64-bit ifort. So, check the naming of
intel compiler programs and the PATH env. variable.
