Errr. That's not so easy. You need the 10.5 SDK which you can only get with a *really* old version of Xcode which you probably can't install on anything newer than OSX 10.6. It's possible to put older SDK's themselves into the "right place" but, for something as old as the 10.5 SDK, it may not even work anymore. The only reliabel way to use an old machine with 10.5 or 10.6 and an old version of Xcode, probably Xcode 3.something.

IMHO, at this point, it's best to drop support for PPC for new versions of pd. The *vast vast vast* majority of OSX users have moved on at this point.

That sounds like you're building pd/extra from Pd-vanilla.  I never had any
luck with that build system.  That's part of the reason why I ripped out extra
from Pd-extended and made it a standalone library.  It was much easier to make
it work that way.

Figured this one out, too.  It was a problem of building 64 bit binaries-- I just
ended up building for i386 and the problem went away.

If I'm going to go to the trouble of building for both architectures, then I
might as well go ahead and build ppc, too.  So the real solution would be
for me to remove my current xcode setup and read all the stackoverflow
workarounds telling which older XCode version to setup an environment
that supports building for ppc.
