I'd personally rather put effort into helping sort out the official
packaging situation rather than work on a satellite macOS packaging
effort.
Specifically, I'd rather resurrect the old packaging/macos tree that
was removed (
http://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/revision/15381)
so that it can be worked on. It's a bit annoying that it was removed
rather than just disabling it and letting it to lie fallow in case
people want to work on it. I've got some patches for it that I put on
hold when it went.
I wasn't subscribed to inkscape-devel at the time, so am not clear on
the background/issues/discussion that led up to its removal. If
Martin, ~suv or whoever else could give a summary or link to any
discussion, I'd really appreciate it.
Cheers,
Tim
