Tony, the powerpc is a big-endian processor, so make sure the BYTEORDER gets defined as 4321 by configure (see a Makefile). see dcm.c for code that depends on endianness and make sure the big-endian code gets compiled. i dont think the configure.in script is smart enough to setup the endian order for linux powerpc (it did for powerpc on the mac).
