Do you have 64-bit intel compiler in your system?
If so, then the question is why the --help-fcompiler could not
detect it. Look at the numpy/distutils/fcompiler/intel.py
script in you Python installation tree and try to find
out why --fcompiler=intelem is not detected. First, check
the version_match text and compare with the version string
that the compiler emits.
