I and a few others are working on updating the chirp package in pkgsrc from the last release to a daily snapshot. That caused me to look at our package, and I see that it depends on py-gtk2, which in pkgsrc is marked as python 2.7 only. In general we're trying to have packages be able to build with python 3 when that's doable.

I went to see if we were missing a py-gtk update that let it use python 3, and we have the last PyGTK release from upstream 2.24.0 that actally has source code. I don't understand 2.24.2 but that seems to be windows installers only and no sources.

FWIW, pkgsrc's current dependencies are:

$ pkg_info chirp Information for chirp-20200622:

Comment: Tool for programming Amateur Radio HTs

Requires: py27-serial>=2.7 desktop-file-utils>=0.10nb1 python27>=2.7.1nb2 py27-libxml2>=2.6.27 py27-gtk2>=2.24.0nb33

I looked in the unpacked daily src tarball and didn't find a README that explained what dependencies are required for chirp.

So I wonder:

Are people using py-gtk2 with python 3? Is there some other py-gtk2 I should be finding?

Is there any option to use py-gobject, or some other gtk bindings instead?

Is there any option to use gtk3 instead?

Is anything on the dependency list above spurious/missing?
