I developed a fix that can byte compile only the .py files in site-packages. It involved creating my own version of brp-python-bytecompile, preventing brp-python-bytecompile from running, and running my-python-bytecompile instead.

The relevant statements in the spec file are as follows:

Before the description insert (from the Fedora packaging python page):

# Turn off the brp-python-bytecompile script %global __os_install_post %(echo '%{__os_install_post}' | sed -e 's!/usr/lib[^[:space:]]*/brp-python-bytecompile[[:space:]].*$!!g')

At the end of the %install (following copying of the doc directories into the buildroot) insert:

~/my-rpm-macros/my-python-bytecompile

The code for my-python-bytecompile is simply a copy of brp-python-bytecompile with the final section commented out. That section does files in directories other than site-packages. The code is below.
