Jay,

I haven't run into this problem before. I have successfully built
with gcc 3.0.x before, so it isn't clear if that is the problem. Is
it possible that one or more of the libraries you are linking against
was compiled against an incompatible glibc or something? In fact,
looking at it the problem seems that libnsl.so and libresolv.so do
not seem to be finding stuff they require in the glibc that you are
using.

When I run into problems like this, I usually ferret around using the
nm command (which dumps all the symbols in an object or library file)
to find what is calling the missing functions.

eg.
nm core/*.o | grep strndup

However, this doesn't work on stripped shared libraries like your
/usr/lib/libresolve.so and /usr/lib/libnsl.so are likelely to be.

Good luck,
