Issue with abort calls when using f2py command

[Bernardo Pacini]

I can successfully build and run my code using the f2py-f90wrap command:

f2py-f90wrap --fcompiler=$(FF90) --build-dir . -c -m _${PYTHON_MODN} -L. -lsrc f90wrap*.f90 

However, when I use only the f2py command as:

f2py --fcompiler=$(FF90) --build-dir . -c -m _${PYTHON_MODN} -L. -lsrc f90wrap*.f90

I run into a namespace error for the abort function call:

>>> import helix_pyf90
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/bernardo_pacini/Documents/HELIX/python_src/helix_pyf90/__init__.py", line 2, in <module>
    import _helix_pyf90
ImportError: dlopen(/Users/bernardo_pacini/Documents/HELIX/python_src/_helix_pyf90.so, 2): Symbol not found: _f90wrap_abort_
  Referenced from: /Users/bernardo_pacini/Documents/HELIX/python_src/_helix_pyf90.so
  Expected in: flat namespace
 in /Users/bernardo_pacini/Documents/HELIX/python_src/_helix_pyf90.so

I am not using the -a/--abort-function flag in either case.

Thank you
