[f2py] f2py -c --help-fcompiler does not detect intel fortran 64 on Mac

Hello everyone,
I have iMac with  snow leopard an intel Fortran 11.1. When I try to execute command f2py -c  --help-fcompiler the output is following  

$ f2py -c --help-fcompiler

I suppose that  --fcompiler=intelem  Intel Fortran Compiler for EM64T-based apps must be appear in "fortran compilers section"

 What am I doing wrong?

Thanks in advance
