Subject: mex files built with fortran having problmes linking in 3.2.2

I am having problems createing a  "mex" file that can access the mx
functions .

A simple example is in the dist examples
 mkoctfile --mex myfevalf.f

octave --quiet --eval myfevalf
warning: mark_as_command is obsolete and will be removed from a future
version of Octave
error:
/afs/pbcell/home/mcoyne/.gnome-desktop/octave-3.2.2/octave-3.2.2/example
s/myfevalf.mex: undefined symbol: mxgetstring_
terminate called after throwing an instance of
'octave_execution_exception'
panic: Aborted -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Aborted

the mxgetstring_ is the fortran call to the c++  mxGetString ? 
How do i build ? is there a library to link against? Or alteritibly what
would be the correct wrapper function to generate the mxgetstring_
function calling the C++ mxGetString function?

My platform is Rhel5 w/ gnu gcc/gfortran  4.4.1
