I will John, but I think I need another day for doing that. Yesterday I changed 
src/Makefile.in for myself and was able to compile all of the Octave sources. 
This is just FYI, I've attached 9534.diff which is the "hg diff -r 9534 
src/Makefile.in >9534.diff".

BTW, thanks for taking such linking issues directly into Octave build scripts, 
even if they don't exist on all platforms. That definitely makes a packager's 
life much easier ;)

-lexpat "or" -lxml2 is a dependency of -lfontconfig, I don't know if this in a 
general issue or if I need to fight such things for myself?

ME$ otool -L /Applications/Octave.app/Contents/Resources/lib/libfontconfig.dylib
/Applications/Octave.app/Contents/Resources/lib/libfontconfig.dylib:
       /tmp/deps-i386/lib/libfontconfig.1.dylib
       /usr/lib/libiconv.2.dylib
       /tmp/deps-i386/lib/libfreetype.6.dylib

       /tmp/deps-i386/lib/libexpat.1.dylib
       /usr/lib/libgcc_s.1.dylib

I'll be back again with results
