OK, I'll change it.

If "myprog" uses the ports framework (including the ports Makefiles), it
will be possible to write something like:

$FC -o myprog myprog.f90 -L${LOCALBASE}/lib $LAPACKLIB $BLASLIB
and pick the default ones.

But if you develop your programs out of the ports mechanism, nothing
will change.
