OK, so looking closer...
The OVS build process runs a few Python programs using syntax like this:
PYTHONPATH=$(srcdir)/python:$(PYTHONPATH) python program.py
This means that sys.path ends up looking like:
['/dir/for/program.py', ..., '/usr/lib/python2.7/dist-packages', ...
'$(srcdir)/python', ...]
where /usr/lib/python2.7/dist-packages is the distro's Python package
installation directory, which is where the python-openvswitch package
installs its .py files. This has the effect that these installed files
override the ones in the source directory.
Python experts, what's the best way to get $(srcdir)/python ahead of
/usr/lib/python2.7/dist-packages in sys.path?
Thanks,
Ben.
