[re-added fink-devel, please try to keep the list in CC] Well, if you want to convince yourself that all the linked libraries are actually needed, you can try it once with LDFLAGS=-Wl,-dead_strip_dylibs and check to see if any of the libraries were removed by looking at before and after otool -L output, you may find this useful to satisfy your own curiosity. However, it is not necessary to do so, and anyway, if the "extra" libraries are coming from pkg-config or libtool's .la files, you will still have to BuildDepend on those packages because without them the build would fail.
