Dear Aaron,
Here's what I did in detail. I downloaded gfortran 4.3 from http://hpc.sourceforge.net/ and that installed fine. Simple programs compile.
Is your gfortran older or more recent than the official one on http://gcc.gnu.org/fortran/ ? -- Dr. Christian SIMON, Maitre de Conferences Laboratoire LI2C-UMR7612 Bat.
