Despite the overall lower quality and usability of 10.9+, I don't see how, since MP in 10.8 can be configured to use libc++.

I don't remember the exact error, but it failed to compile — it succeeded when I upgraded the base from 2.3.x to 2.4.1.

OS X 10.8.5, Xcode 5.1.1, MP 2.4.1 — no differences that come to mind.

Should I expect to encounter problems when switching to building from source with libc++ for the same ports whose binaries work fine with libstdc++?
