Thanks for the detailed analysis !
It seems a workaround is to provide an install command that creates those
.pyo files upfront, so they find their way into the INSTALLED_FILES list.

Thus, I tried 'python setup.py bdist_rpm --install-script=install',
where the content of 'install' is
'python setup.py install --optimize=1 --root=$RPM_BUILD_ROOT --record=INSTALLED_FILES',
and voila ! It works !

Not sure whether it is worth holding your breath for someone to fix distutils. :-(
