The issue is that GMP 4.2 compiles with:
using ABI="mode64"
CC="gcc"
CFLAGS="-m64 -mcpu=970 -fast"
CPPFLAGS=""
CXX="g++"
CXXFLAGS="-m64 -mcpu=970 -fast"
MPN_PATH=" powerpc64/mode64 powerpc64/vmx powerpc64 generic"
If one reads the documentation, one finds that -fast implies -mdynamic-
no-pic, which generates object files that are not suitable for use in
a dylib. The gcc man page has:
To build shared libraries with -fast, specify -fPIC on
command
line.

David,
I think I have solved the problem. I thought the use of only
-fno-common in gmp to compile shared libs looked suspect. Sure enough
if I compile gmp 4.2 with...
...the resulting build fully passes make check on the G5. I don't
believe that -fno-common provides PIC code in the same fashion as
-fPIC. Googling those flags show a lot of code using both -fPIC
and -fno-common in the compiles.
