Matlab: command mex -setup can't find my C compiler

I use the mac R2009b and gcc -4.16 and xcode.

>> mex -setup

    Options files control which compiler to use, the compiler and link command
    options, and the runtime libraries to link against.

    Using the 'mex -setup' command selects an options file that is
    placed in ~/.matlab/R2009b and used by default for 'mex'. An options 
    file in the current working directory or specified on the command line 
    overrides the default options file in ~/.matlab/R2009b.

    To override the default options file, use the 'mex -f' command
    (see 'mex -help' for more information).

The options files available for mex are:

1: /Applications/MATLAB_R2009b.app/bin/gccopts.sh : 
    Template Options file for building gcc MEX-files

2: /Applications/MATLAB_R2009b.app/bin/mexopts.sh : 
    Template Options file for building MEX-files via the system ANSI compiler

0: Exit with no changes

Enter the number of the compiler (0-2):

Somebody can help?
