[SciPy-user] f2py problem: failed to map segment from shared object: Operation not permitted

I am trying to reuse some old code.  I am running into a problem importing a
module created by f2py.  Here is the traceback:

/home/ryan/pythonutil/rwkmisc.pyc in my_import(name)
    347
    348 def my_import(name):
--> 349     mod = __import__(name)
    350     components = name.split('.')
    351     for comp in components[1:]:

ImportError: /home/ryan/thesis/sym_control_design/fortran_model_bode1f.so:
failed to map segment from shared object: Operation not permitted
WARNING: Failure executing file: <symbolic_modeling.py>

I just tried recompiling the code.  The output of "f2py -c -m
fortran_model_bode1f fortran_model_bode1_out.f" is below.  Note that g77
doesn't show up in my Ubuntu 9.04 package manager.  I have gfortran
installed.  Can I safely ignore all the messages about not finding various
executeables since it eventually finds gfortran, or is this part of the
problem?  Recompiling did not fix my problem.  The fortran file is attached.

Thanks,

Ryan
