Hi!

You can do something like this (takes 2-seconds):

lrwxr-xr-x  1 root  wheel      22 Oct 23 18:13 /usr/local/lib/libusb-0.1.so.8 -> /usr/lib/libusb20.so.1
lrwxr-xr-x  1 root  wheel      19 Oct 23 18:14 /usr/local/lib/libusb.a -> /usr/lib/libusb20.a

Others have suggested doing this using libmap.conf.
