I noticed an error in the harfbuzz module yesterday that was causing it to build before glib. It has a soft dependency on glib, but not having it might cause trouble with pango (harfbuzz shapes the font, pango lays it out and displays it on a cairo surface). You may have picked up the change with your latest build: Check that "hb-glib.h" is in $PREFIX/include/harfbuzz.

I'm firing up a Tiger build on PPC to see if I can replicate the problem.

As a first step I was able to build for ppc only and the 10.5/10.5 SDK without any problems ("jhbuild bootstrap && jhbuild build meta-gtk-osx-bootstrap && jhbuild build meta-gtk-osx-core" succeeds without any issues).  I am trying the universal build next.

Ah, I'd forgotten that you'd been doing universal builds.
