That part is easy enough. If you want a framework build you'll have to patch Makefile.pre.in because it contains a hardcoded '- arch ppc' in the section that builds that actual framework. Otherwise it should just build (assuming you have an intel mac of course, cross-building from PPC to Intel will be hard because the build process assumes you'll do a native build).

ok, I found the relevant part in configure (and cofigure.in) that was putting -arch_only ppc into the Makefile and I've re-run configure and it seems happy - heck, even the compiling ran error free.

But when it got to the link part - I get the following error:

You must replace the -arch ppc part by -arch i386. If you want to build a universal binary you'll have to replace the call to libtool by something more complex. I'll see if I can produce a patch later today.
