compile error on mac ppc box

Mon May 6 09:00:20 PDT 2013

Hi Tony,

you should definitely use the gcc tool set. For details you can have a
look on how the current MacOS port is build on x86.

The big challenge would be to combine OS-wise the BSD parts of the
current JDK7 MacOS port with the CPU-specific PPC parts of the ppc-aix
port.

Regards,
Volker
