[f2py] Hello; f2py on Mac OS X with gfortran

[Andreas Voellmy]

Thanks for the tip. 

I installed the g77 version into /usr/local/bin. Running
/usr/local/bin/gyy --version gives:

GNU Fortran (GCC) 3.4.4

Then I ran gcc_select 3.3. Now when I run gcc_select it shows: 

Current default compiler:
gcc version 3.3 20030304 (Apple Computer, Inc. build 1809)

Then I ran f2py like this: 
f2py -f77exec=/usr/local/bin/g77 -c -m hello hello.f

It has an error on linking saying: 
g77: installation problem, cannot exec 'c++filt': No such file or directory. 

It creates the hello.so file anyway. I started python and imported
hello, then got this error:

Fatal Python error: Interpreter not initialized (version mismatch?)
Abort trap

What am I doing wrong? It looks like the versions are still a problem.
Is my machine still not using the correct compiler?

Thanks! Andreas
