How do I compile some specific package with my custom CFLAGS? Other searches suggest that I should just edit the formula by hand but I don't want to do because I want a solution that easily works in all cases.
Or do they strictly not want to allow custom CFLAGS? This suggests it.
Esp., in my case, I just want to pass one of
--with-macos-sdk=/Developer/SDKs/MacOSX10.6.sdk to CFLAGS because I want to build a library which is compatible with >=MacOSX 10.6.
