Comment:
Yes, xlint is wrong about `pycompile_module="gtk-2.0/gtk"`, it is set here to avoid compiling whole gtk-2.0 that is shared between packages,. Please add comment and ignore warning.
`pycompile_module="demos"` should be removed because demos is not in site-packages/; `pycompile_dirs="usr/lib/pygtk"` should be set here.
