Wow, that was quite a lot to read (or skim ;)).
A few observations that might help:
 * Building poppler seems to work fine. As I had speculated previously,
it builds more than it has to, and there are some warnings, but
poppler-qt4 seems to work fine. Also, I didn't see any reference to Qt
4.3 except in "libpoppler-qt4.3.dylib", so maybe the poppler devs are
indeed just lazy in update the Mac filenames.
 * GCC versions seem to differ. When building hunspell, for example, the
command called is "g++". When building Tw, the command is
"/usr/bin/g++-4.0". If these are indeed different compilers, the error
"file was built for unsupported file format" seems explainable. The
custom compiler for Tw is defined in TeXworks.pro lines 66 & 67. Just
comment those out (prefix by #) and try again (you may have to do a
clean rebuild, i.e. repeat the compilation). IIRC, that settings had
something to do with supporting Mac OS 10.4.
 * Linking for ppc apparently fails because the Qt libraries are not
built for that architecture (evident from "/usr/lib/libQtUiTools.a,
missing required architecture ppc in file" and the fact that just about
any symbol is "undefined). Disable it for now by removing "ppc" in
TeXworks.pro on line 84 ("CONFIG += x86 ppc").

Thanks for trying, and for sharing all the build logs. They have been
really helpful!

Have a good conference!

same problems some hints.
