Hi All, I'm having some difficulty building on OSX 10.8 (Mountain Lion)

It is the QT version causing me some problems, if I use 4.5.1, I cannot build because mountain lion is not supported, and if I use 4.8.1, I get the MOC error shown below.

Has any one got any advice?

Here is the end of my build output:
