problem compiling MuseScore

I'm trying to compile MuseScore for the first time on my mac.
I've installed Qt version 5.4, but when I try to compile it claims I need Qt 4.
Is this correct? Do I need to install exactly this version of Qt? Or do I simply need to install Qt 4 along with the newer version 5.4 to satisfy the make file.

Here is the compilation log.

I'd appreciation any clues someone might give me.
