help needed: Updating pyqt to 4.11.1

Unfortunately this fails to compile (on Mavericks) with the following linker error: http://pastebin.com/rWmepPhu

Possibly this is related to Homebrew building with the custom libc++ makespec.

Any ideas?
I removed the custom qt makespec since on my system it seems to compile fine with libc++; this however is with configure-ng.py; @dakcarto, do you believe the custom makespec is still needed such that the generated pyqtconfig.py is generated correctly? Do you have a way of testing it, maybe with QGIS?
