I don't see how that explains that 1.6.4_0 in one system is the binary from MP, but this same version fails to compile in another identical system. OS X 10.8.5, Xcode 5.1.1.

And neither does it help me to decide if it'd be better not to switch to compile from source and break other ports down the line.
