It appears you have (or had) more than 1 version of gfortran
on your system.  The driver program named 'gfortran' can't
find its libraries, and is finding old out-of-date libraries.
You might try 

which gfortran
/full/path/to/gfortran --version
/full/path/to/gfortran -v some.f

Next remove all files found by 

find /usr -name \*gfortran\*

and re-install gfortran.  Unfortnately, you may need to 
re-install software that used gfortran (ie., lapack).
