Code:

Make

and

Code:

Make install

I would run

Code:

gcc -WI,-rpath,"/usr/sfw/lib"

?
How would I install it then, can I run 'make install'?

Sorry, I didn't notice your reply until now.
YOu edit the Makefile to add the rpath snippet either to the LDFLAGS variable or directly to the line that builds the binary. You should find a pair of lines like this:

Code:

apcupsd:  $(OBJS)
          $(CC) ... -o apcupsd ...

If the library is explicitly mentioned (rather than being hidden in say $(LIBS)) put it just before that:

Code:

... -Wl,-rpath,"/usr/sfw/lib" -lusb ...

You then use make and make install as before
