Looks like there is an "install_pkgconfig" target... So just:
python setup.py install_pkgconfig #as root
or
python3 setup.py install_pkgconfig #as root
Ahh, just tried to build pygobject3. The pycairo instructions need also:
python setup.py install_pycairo_header #as root
python3 setup.py install_pycairo_header #as root
Both lines are needed since the files installed are not the same (py3cairo.h
or pycairo.h.
Now pygobject builds OK. Trying to build gimp (book version, not RC). Will
report.
