Re: GCC build on darwin12.3

[Nenad Vukicevic <nenad at intrepid dot com>]

Are you using Mac ports for gmp/mpfr/mpc libraries?  I see that
you have "-L/opt/local/lib" on you path.

I had the same issue and as I recall it was related to installing
iconv mac port package and incompatibility of iconv.h header
files.

I switched to building gmp/mpfr/mpc from sources and not installing
mac ports. Alternatively you can run contrib/download_prerequisites.
