Matlab might try to use its local /Applications/MATLAB_R2011b.app/sys/os/maci64/ fortran libraries
instead of the gfortran package libraries.  Matlab library is missing some symbols, so you might
need to link to the actual gfortran library 
sudo cp /Applications/MATLAB_R2011b.app/sys/os/maci64/libgfortran.3.dynlib /Applications/MATLAB_R2011b.app/sys/os/maci64/libgfortran.3.dynlib.matlab
sudo ln -s /usr/local/gfortran/lib/gcc/x86_64-apple-darwin10/4.6.2/libgfortran.3.dylib libgfortran.3.dylib
