[chirp_devel] pygtk installed, but chirpw wants gtk

Hey folks, sorry if this is an obvious question. I'm fairly new to GTK development and only slightly more knowledgeable about Python.

I'm trying to build a Chirp flatpak. Flatpaks are sandboxed, cross-distribution packages that are gaining a bit of momentum in the GNOME/KDE worlds. While flatpaks ship Python GTK support, they use the newer GI and don't use the older module. I manually install pygtk 2.24.0, but it installs such that "import pygtk" works but "import gtk" doesn't.

I wonder if this means I'm doing the installation wrong, or are these two distinct modules? I wonder if chirpw might try importing pygtk if plain gtk fails?

Thanks.
