In MacPorts we already do the usual linking and there it already works
(without rpath, it just links to /opt/local/lib/libgs.dylib, end of
story).
But if we cannot guarantee that libgs will exists, we cannot use this
trick, I guess.

I assume that dvisvgm could be modified in some way to also check some
predefined prefixes. It would not look too elegant though.
