powerpc-apple-darwin8-g++-4.0.1: unrecognized option '-rdynamic'
But it just ignored the option and proceeded anyhow.
grep shows that it was added to LDFLAGS coercively by configure.ac.
Don't think this is a good idea in general.
Why not use GNU libtool, where it adds the Right Flags (TM) as it deemed
necessary?

Anyhow, attempting to run the built src/gnucap (before installing),
I get:

% ./gnucap
incorrect link order
Abort

% gdb ./gnucap
(gdb) run
Starting program: /Users/fang/local/src/gnucap-2007-02-21/build/src/gnucap

I'm not well-versed in the source, but are you depending on ordering of
static globals somehow?
