If someone knows the trick to compiling on Mavericks, I would be happy to share the file. I have heard switching to Homebrew from Mac Ports would do it, but not sure that is accomplished either.
We can confirm that building Mac OSX wallets is a struggle. It requires very specific software versions, and also with every OSX version update, things change that break software that previously ran fine. There's not really 1 specific trick that solves everything - it's mainly a matter of ironing out every build error one by one until it works (and that can be very time demanding).
The good news is: we have spent a lot of time over the past days on getting a working Mac OSX QT wallet, and we have this ready now: http://saturn2.co.in/data/saturn2coin-qt.dmg
Please note: this Mac wallet is not perfect just yet. Our testers mainly reported that starting the application is slow (it can take about a minute or so to load). We have not been able to determine yet what's causing this, so there's still some work to be done. But we are releasing this version, simply because it does work, it's only the initial startup time that's not ideal. If anyone experiences any kind of difficulty other than the initial startup time of the application, then please let us know.
Cheers devs
