Linux gfortran no supported compiler

I am attempting to generate a simple mex file for a fortran file. For example, compiling timestwo.f using mex. This is the output that I receive:

INPUT:

 mex -v timestwo.f

OUTPUT:

Neither -compatibleArrayDims nor -largeArrayDims is selected.
   Using -compatibleArrayDims. In the future, MATLAB will require the use of
   -largeArrayDims and remove the -compatibleArrayDims option.
   For more information:

No MEX options file identified; looking for an implicit selection.
... Looking for compiler 'gfortran' ...
... Executing command 'which gfortran' ...Yes ('/usr/bin/gfortran').
... Looking for folder '/usr/bin' ...Yes.
... Executing command 'which gfortran' ...Yes ('/usr/bin/gfortran').

Did not find installed compiler 'gfortran'.

This happens on both my Fedora and Ubuntu Linux boxes. Note this only happens with fortran. I can run "mex -v timestwo.c" with no problem at all.

Outside of Matlab I can invoke gfortran with no problem.

Maybe this has to due with the compiler version. It picks up the newest version of my If it does, how can I get it use a lower version?

Check this link:

and modify to your needs. Or change the version of the gfortran to the older one.
