Thanks Ryan. I am torn whether to keep WORDS_BIGENDIAN in the code. Perhaps, I will just leave it in the code and see if anyone reports bugs.
This code was compiled my Metakine into a ppc/x86 FAT binary and run without issues for many years. So I suspect the WORDS_BIGENDIAN macro was never used in the code since as you pointed out Intel Macs are little little-endian.

I see that ARCH_PPC is used in mpeg2dec/mpeg2_internal.h. I agree I don't see anywhere that ARCH_X86 is used. > I will check whether the code uses WORDS_BIGENDIAN.

Code that process endianness incorrectly will probably still compile and run but will generate incorrect data. So just the fact that it compiles doesn't mean it's right. > My portfile already had PortGroup makefile 1.0 so there was no need > to add it. Ah, yes, I missed that. As you've now found, using the makefile portgroup means there's no need for you to list "use_configure no"; the fact that you had still listed "use_configure no" lead me to the incorrect assumption that you had not used the makefile portgroup.
