bmpx ebuilds use --disable-python directly. It could build the python bindings.
Created attachment 99494 [details, diff] bmpx-python-bindings.patch Patch against bmpx-0.32.0.ebuild. It works fine for me at compilation time, but I haven't tried if it actually works at run time.
Please, use unified diffs, way more readable. ;)
Is there any particular reason you need them? There is nothing using them in the tree at the moment. Will probably add them in the next version.
No, I don't use them and don't know if there's anything using them. I filed the bug as a reminder.
