I want to create RPM spec file that lets the user build the RPM with an
alternate prefix - e.g.
rpmbuild -D '_prefix /opt/whatever' -bb package.spec
That results in in the python files being placed in
/opt/whatever/lib/pythonN/site-packages and
/opt/whatever/%{_lib}/pythonN/site-packages
Those directories are outside of the default python search path.
I could leave it up to the user to add them, but its nice when
installing a package just works (hence why we can put files in
/etc/ld.so.conf.d for example) without the user needing to fuss too much.
When the user builds with a different prefix, there likely will be
several different packages that put python stuff in that prefix, so a
meta package they require that adds to the search path is what I am
thinking, that both adds to the python when installed and removes it
from the python search path when removed.
