I already reported that the submodule does not configure on OSX/ppc
v10.5.8 - apparently due to some PKG_ macros not getting resolved. I
suspected aclocal not picking up pkg.m4 file but setting ACLOCAL_FLAGS
did not help. Do we need a more modern pkg-config version than we are
testing for?
Another issue seemed to be that our Makefile did not take into account
that I may be building with, e.g., "gcc -arch ppc64" and passing a
specific $PATH for 64-bit libraries / aclocal / pkgconfig to our configure.
The latest stable pixman configured but didn't compile on OSX/ppc due to
undefined identifiers or something. (The broken submodule version makes
it unhandy to fix this.)
This is holding up my Cocoa review of the gfx_ hook (that you haven't
jumped in to help out for v1.3) and I seriously doubt that it makes any
difference if I go through the hoops of posting the same info on
Launchpad when it Simply Works(tm) on Linux distros...
Testing on OSX/i386 v10.6 is still on my TODO list.
