You are mixing incompatible gfortran and gcc versions.

Here is gfortran:

configure:2769: gfortran --version >&5
GNU Fortran (GCC) 4.2.3

configure:2780: $? = 0
configure:2769: gfortran -v >&5
Using built-in specs.
Target: i686-apple-darwin8
Configured with: /Builds/unix/gcc/gcc-4.2/configure --prefix=/usr/local
--mandir=/share/man --program-transform-name=/^[cg][^.-]*$/s/$/-4.2/
--build=i686-apple-darwin8 --host=i686-apple-darwin8
--target=i686-apple-darwin8 --enable-languages=fortran
Thread model: posix

And here is gcc:

configure:3872: gcc --version >&5
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build
5658) (LLVM build 2336.11.00)

As you can see, gfortran is 4.2.3 and gcc is 4.2.1. In addition,
gfortran is building for i686-apple-darwin8 and gcc is building for
i686-apple-darwin11 and will likely be unable to link their results
together into a final binary. You will need to fix your paths so that
the correct and compatible compilers are found.
