Thanks for your quick reply. I noticed that I accidently used the
wrong Makefile. Instead I now use the correct on that was create by
the configure script. Unfortunately I still get an error that seems to
be related to the fortran libraries but I'm not shure about that.
This is what the Makefile looks like

# INSTRUCTIONS: Please modify the following few variables. See the
# readme.html file for more information.
# This variable corresponds to the base directory of your MATLAB
# installation. This is the directory so that in its 'bin/'
# subdirectory you see all the matlab executables (such as 'matlab',
# 'mex', etc.)
MATLAB_HOME = /net/matlab/Matlab2011b
# Set the suffix for matlab mex files. The contents of the
# $(MATLAB_HOME)/extern/examples/mex directory might be able to help
# you in your choice.
MEXSUFFIX = mexa64
# This is the command used to call the mex program. Usually, it is
# just "mex". But it also may be something like
# /user/local/R2006b/bin/mex if "mex" doesn't work.
MEX = $(MATLAB_HOME)/bin/mex
