[chirp_users] Python 3? GTK3?

[Greg Troxel]

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:

  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?
