Ah, well, I did not understand this is part of NumPy.

In the way we treat python software, a port is meant to either:

a) provides a python module (with pyXY-* subports)
b) provides a standalone tool (with optional +pythonXY variants)

In this case, py-numpy provides both modules and tools, so the outcome
is not ideal. You end up with the suffixed tools as multiple pyXY-numpy
ports can be installed at the same time for different python versions.

Other ports such as ipython, pyflakes, pylint provide their own select
files.
