I wondered whether starting configure time library path with "./" would be
a good sign that you wanted it relative to something.
However, "something" may well be "../lib" relative to the directory where
the perl binary is, so maybe starting with not "/" treats it as relative to
the directory where the perl binary is.

Is this enough ? It only lets one have libraries in one of
two places - fixed absolute, or fixed relative to the perl binary.
