The symbols reported as undefined are in "/usr/lib/libSystem.dylib",
which is also symlinked as "libc.dylib".  Did something leave out
a library reference?  Or mask it?  "libSystem.B.dylib" also contains
the symbols claimed as undefined.
>How-To-Repeat:
Attempt to build math/pari on MacOS X 10.4.11 (ppc), or any package which
pulls it in as a dependency (net/clive in this particular case).
