POWERPCG4 is false on powerpc64. The FTBFS on ppc64 comes from the 'CXXFLAGS=-mcpu=750'. The package builds on ppc64 if that single line is commented out. To avoid changing the 32 bit powerpc case, a special alternative for powerpc64 could be introduced. On the other hand I think that using -mcpu is almost always a bad thing. I am not sure if the current -mcpu settings really make sense on 32 bit powerpc generally. The altivec setting may be useful if it is available, though.
