Ah, okay. We do use the md5 module in part of the build process. See
numpy/core/code_generators/genapi.py . If you just need to get something built,
you can modify that file to use a different hash. You could write your own that
does something extremely simple like keep the strings in a dict mapping to
numbers that you increment.
However, your Python installation is broken. hashlib is a standard module that
should exist in all Python installations.

an underlying truth."
