I was with you till the "very easy" part.  Been following the updates today
and noted that (earlier) the portion of INSTALL that detects the
architecture on Darwin was not working.  Had a patch for that and
regrettably blew it away (accident), then had to turn my attention to
something else.

May try again tomorrow if it persists...

As for the Cocoa bits (mmmm cocoa bits) I might get some time to work that a
bit this weekendif no other takers rise up.
