After not much luck with 7.1.x, I've successfully compiled 7.2.0 on Mac/PPC, openSUSE 10.3 64-bit & openSUSE 11.0 32-bit.
All using the following configure options:
./configure --disable-glibc-version-check --disable-gcc-version-check --disable-full-port --without-classads --without-gsoap
All I need to do now is test it on my pool, but looks promising so far!
