setuptools (was distutils...) and AIX - getting to PEP427 or PEP491

Starting a new thread - I think the first one has served it's purpose.

I use, successfully, pip build; pip install to build and install modules
for Python. The files "installed" by pip install (to .../site-packages)
I repackage as installp (AIX installp manager) packages.

This works - but - requires root access (to execute installp) and I do
not expect this will support anything like virtualenv.

Further, sometimes a .egg-info file is created, sometimes not. And when
it is created it does not always include an "AIX" tag.

As example, I show some data from the modules I "pip built and
installed" and then repackaged as installp:

root@x066:[/home/root]lslpp -L | grep python3 | grep -v adt | sort
  aixtools.python3.asn1crypto.rte
  aixtools.python3.bcrypt.rte
  aixtools.python3.cffi.rte
  aixtools.python3.cryptography.rte
  aixtools.python3.paramiko.rte
  aixtools.python3.pycparser.rte

  aixtools.python3.six.rte  1.12.0.0    C     F    tools six 26-Jul-2019
root@x066:[/home/root]find /opt/lib/python3.7 -name \*.egg\*
/opt/lib/python3.7/site-packages/cffi-1.12.3-py3.7.egg-info
/opt/lib/python3.7/site-packages/cryptography-2.7-py3.7-aix-6.1.egg
/opt/lib/python3.7/site-packages/pycparser-2.19-py3.7.egg-info

There are no .whl (except for pip and setuptools).

I am starting to guess that getting a wheel built requires more than
what most packages are doing.

Further, I am sure cffi should be including an AIX platform tag - as it
generates a .so file that depends on standard libraries from AIX (libc
and libpthreads).

I'll have read up on what is actually in the egg-info (using od -c I can
read the file).

Seems to be very close to what I find here

root@x066:[/opt/lib/python3.7/site-packages/cryptography-2.7-py3.7-aix-6.1.egg/EGG-INFO]ls

++++++

In short, I am just a user of pip and setuptools - but I would like to
utilize them for packaging "binary" modules for AIX that do not require
installp (or the alternate package manager - rpm).

Some pointers into the documentation that is essential (I am starting at
https://setuptools.readthedocs.io/en/latest/, but seems like quite the
mountain!).

Thanks (for remembering what it was like when you first started!),

Michael
