There is a "rpath" of sorts in older Mac OS X too, and it can be tweaked
by using install_name_tool on the binaries after building for instance*.
If you look at the wxLua "distrib/macbundle/copydylibs.command" script,
it changes the location of the libs when installing the .dylib (=.so)

It changes the default linker path of /usr/local/lib/libfoo.dylib
into a local path like @executable_path/../../../libfoo.dylib
(where the "@executable_path" string is automagically replaced
with the location of the current program, on application start)

The extra two .. levels is for "wxFoo.app/Contents/MacOS/wxFoo",
i.e. to break out of the directory structure of the app bundle

--anders

* it can be set when building too, but I never got around to
   hacking the necessary flags to do so into the Makefile :-)
