You know, I'd be willing to do that. Do you know of a good tutorial on this?
No need to compile GTK, etc. yourself. Homebrew has you covered.
brew tap caskformula/caskformula
brew install caskformula/caskformula/inkscape
Mentioned at the bottom of the page [1].
There are flags to do just that, but it's a very lengthy process, because you have to compile GTK and other libraries first.
It works well, although there are occasional bugs, such as the shortcut keys using Ctrl instead of Cmd, if I recall correctly.
