Can you quote the complete gcc command line that outputs the above ld
errors?

missing from the above g++ command line.
You link against
@__________________________________________________URELIB/libuno_cppuhelpergcc3.dylib.3,
which really is
/Applications/OpenOffice.org.app/Contents/basis-link/ure-link/lib/libuno_cppu.dylib
(the -Wl,dylib_file,@... already present), which has a dependency on
@loader_path/libuno_sal.dylib.3, which ld wants to resolve, and it
appears that ld does not figure out the correct value for "@loader_path"
itself (although it probably could) and you must instead also tell it
explicitly (via the additional -Wl,-dylib_file,@loader... that is
missing) where to look. Also see
solenv/bin/macosx-dylib-link-list.pl:1.3 which computes the necessary
-Wl,-dylib_file arguments in OOo builds.
