Configuring fails on missing mpc.h on Mac OS 10.5.8

Yes, it is new, see http://gcc.gnu.org/ml/gcc/2009-11/msg00823.html.

I think the 'mpc' that you find in macports is a different thing than
what GCC requires (namely some kind of audio tool). Try 'port info
mpc'. I have not been able to find mpc (the multi-precision library
for complex numbers) in the macports repo.

You should consider building mpc from source (available from
http://www.multiprecision.org/).
