Comment (by anksil):

 Is there any kind of workaround for this? It's a bit of a blocker for both
 us and those of our customers who use Mac. We do have old binaries to fall
 back on, but they're not very up to date and don't support X11 forwarding.

 I've tried to dig through both Xcode settings and the MacPorts config
 files and file trees, but I feel like I'm way out of my depth.
