Shall I rename mex to omex so there is no conflict?

By default octave-forge installs in an octave version specific
directory.

Version (not that you should need it):

        $ echo "disp(OCTAVE_VERSION)" | octave -qf
        2.1.55

m-file install paths (use localfcnfiledir):

        $ echo "disp(octave_config_info.localverfcnfiledir)" | octave -qf
        /usr/local/share/octave/2.1.55/site/m

        $ echo "disp(octave_config_info.localfcnfiledir)" | octave -qf
        /usr/local/share/octave/site/m

oct-file install paths (use localveroctfiledir):

        $ echo "disp(octave_config_info.localveroctfiledir)" | octave -qf
        /usr/local/libexec/octave/2.1.55/site/oct/powerpc-apple-darwin7.2.0

        $ echo "disp(octave_config_info.localoctfiledir)" | octave -qf
        /usr/local/libexec/octave/site/oct/powerpc-apple-darwin7.2.0

supporting binaries paths (use localarchlibdir):

        $ echo "disp(octave_config_info.localverarchlibdir)" | octave -qf
        /usr/local/libexec/octave/2.1.55/site/exec/powerpc-apple-darwin7.2.0

        $ echo "disp(octave_config_info.localarchlibdir)" | octave -qf
        /usr/local/libexec/octave/site/exec/powerpc-apple-darwin7.2.0


I put these notes on the wiki at

Please add more detail there as you see fit.
