Two different Fortran compilers being used

While running "make" I got these errors:

   ./.libs/libISSMCore.so: undefined reference to `e_wsfe'
   ./.libs/libISSMCore.so: undefined reference to `do_fio'
   ./.libs/libISSMCore.so: undefined reference to `s_wsfe'

Mathieu tracked this down to be the use of two different compilers while compiling the external packages: gfortran and g77. To solve this, I added the following lines to my ~/.bash_profile:

      export F77='gfortran'
      export FC='gfortran'

Then, "source ~/.bash_profile" and reinstall all external packages, make clean, configure, make, and make install.
