here is a patch for current git that should make the automake functional again.
note: when doing a "make install", the "pd" binary only get's installed into
/usr/local/bin/pd (by default) and not into /usr/local/lib/pd/bin/pd; this is
not a problem unless you try to start Pd from the gui-side (pd-gui will only
look into /usr/local/lib/pd/bin/pd for the binary)
note: for extra/, i have build on the original makefile by miller, as it seems
to be more extendable than hc's suggestion, which resulted in a rather tedious
enumeration of all the files to be compiled in a centralized file.
