It is theoretically possible to build all the dependent libraries
twice, cross compiling one time, but usually we've been too lazy to
set all that up.  I/we have both ppc and intel macs and do darwinports
(plus a few extraneous dependencies by hand) on each.  Then running
the new script finds the dependent libs and copies them in place for
later lipo'ing as you saw.  It is a bit crude, but it works.

As for your testing discussion, I don't really see a need to do the
whole app bundle thing for that.  Automated testing for an app like
ardour seems a bit ambitious, there are *so* many options and things
that could be done, and missed.  I know that although potentially
valuable, the core developers aren't likely to have time to help much
with that.  But willing contributors like yourself are welcome to give
it a shot!

Not a bad idea.  The app_build.rb was really mostly an exercise in Ruby.
