in case you really want to compile molcas with gfortran - you should use a special configuration file:
./configure -compiler gf
(Note, that gf.comp was developed for 32-bit OS, if you are using 64-bit computer - like AMD64 - some modifications should be made for compilation options, and GATARGET should be set to LINUX64)

However, you should be aware that gfortran generates a code which is 30-40% slower than g77. And molcas is not an exception :(

So, my advice - install GCC 3.4.6
