Errr... I'm not sure how to parse that.  The config.log you cited shows that 
the compiler does *not* work in configure:

-----
configure:29606: checking if Fortran compiler works
configure:29635: /usr/local/bin/gfortran -o conftest    conftest.f  >&5
Undefined symbols for architecture x86_64:
  "__gfortran_set_options", referenced from:
      _main in cccSAmNO.o
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status
configure:29635: $? = 1
configure: program exited with status 1
configure: failed program was:
|       program main
|
|       end
configure:29651: result: no
configure:29665: error: Could not run a simple Fortran program.  Aborting.

Did you typo and mean that the compiler does work when outside of configure, 
and fails when it is inside configure?

Do you have DYLD_LIBRARY_PATH set?
