I’ve heavily updated my KiCad build formula for homebrew, a package manager on OS X that’s sort of like macports if macports was good (KIDDING 
, sorry macports users).
Anyway, at one point, before the stable release and the OS X nightlies, some of you on this forum used it (or at least tried to use it), but it had a lot of issues, especially with older versions of OS X.
I have rewritten the formula from scratch, and finally started using CI tools (travis, jenkins) to check that it works on several verisons of OS X, and at the moment, I am working towards getting it accepted to the official homebrew-science repository. It passes all homebrew tests and will build even on 10.6, but only if you turn off python scripting.
It is very mature and stable now, so for OS X users who use homebrew and want to build an optimized version of the stable release (developer and debug versions) for their system with things like linking to the latest version of python (homebrew’s), menu icons, boost 1.59, etc. that are not in the stable or nightly snapshots, check it out at check it out at https://github.com/metacollin/homebrew-kicad
I know there are 2, possibly 3 people who might want to use it. It’s certainly niche. Its what I use to build the KiCad I’ve been using for a couple months now (I like menu icons heh).
