BUG:

The python package Pillow only has dependences (defined in
reproduce/software/make/python.mk) on the non-python library
libjpeg and on setuptools.py. On some machines, this leads
./project configure to fail the Pillow build on the first run,
with the error message "error: invalid command 'bdist_wheel'". This
forces the user to do a second iteration to complete the full python
build.

DISCUSSION:

Under the three-level python build scheme resulting from discussion
with python developers [1], Pillow is not one of the three
python-low-level packages, and it does not have a dependence on any
python-medium-level packages, so it is not a python-high-level
package. Thus, it is a python-medium-level package, and should have
dependences both on python-installer and on wheel (direct
dependence on setuptools would be superfluous).

(The "level" terminology here is Maneage specific. We can update
to generic terminology if that becomes well defined.)

PROPOSED FIX:

A commit is proposed in [2] on branch bdist_wheel [3].
