Comment 2 for bug 655778

Fixed at lp:mixxx/1.9 r2666

Bad news is that we can't follow OSX aliases (nor Windows .lnk shortcuts). So my changes do a couple of things:
First off, if we don't find an itdb in the proper location, it first sees if a custom itdb path has been saved in the library db. If not, it asks for a path, and saves it.
Of course, this doesn't solve anything for our forumer who has the alias, so I implemented a right click menu on the iTunes sidebar entry that has an option to choose a different library file or use the default one (in case someone chooses to use a different one but later moves back to using the regular location). Hopefully this is a Good Enough (TM) solution.
