Really great progress with all of the OSX support. My laptop died last month and by the time UPS drops of my shiny new MBP (which can actually build Qt in less than a century) I won't have anything left to help with!
In the meantime I've added an OSX TravisCI configuration so any changes to the indi codebase are now verified to compile on OSX.
I spent some time trying to get a TravisCI configuration working for kstars, but the homebrew install of Qt causes timeouts, even when I use the "travis_wait" workaround. Another option would be to bundle up pre-compiled Qt binaries with dbus support and download them instead of using homebrew. Unfortunately, homebrew's dependency system makes this difficult. You can see my attempts here travis-ci.org/seanhoughton/kstars
