OK for example the distribution g95.py in distutils/fcompiler has the  
following code

        executables = {
            'version_cmd'  : ["g95", "--version"],
            'compiler_f77' : ["g95", "-ffixed-form"],
            'compiler_fix' : ["g95", "-ffixed-form"],
            'compiler_f90' : ["g95"],
            'linker_so'    : ["g95","-shared"],
            'archiver'     : ["ar", "-cr"],
            'ranlib'       : ["ranlib"]
            }

For osx you need to modify it to

      executables = {
            'version_cmd'  : ["g95", "--version"],
            'compiler_f77' : ["g95", "-ffixed-form"],
            'compiler_fix' : ["g95", "-ffixed-form"],
            'compiler_f90' : ["g95"],
            'linker_so'    : ["g95","-shared"],
            'archiver'     : ["ar", "-cr"],
            'ranlib'       : ["ranlib"]
            }
    import sys
    if sys.platform.lower() == 'darwin':
        executables[linker_so'] = ["g95","-Wall -bundle"]

The 'shared' option is not implemented in the osx linker. Not sure  
what the underlying difference between 'shared' and 'bundle' is but  
this substitution is necessary and this has been working for me for  
the last year or so. You also need the -Wall but for reasons that  
completely escape me.

The same goes for gfortran and intel (both of which I use) and I  
assume the other compilers that are available for OSX.
