swi-prolog-devel uses system ncurses rather than MacPorts

I did not try the other swi-prolog variants, but I suspect they have the same flaw. The link line should have an -L${prefix}/lib in it

It would normally be OK because we set CPATH and LIBRARY_PATH, but this port changes them and actually puts /usr/{include,lib} first.

Linking seems to be OK in the current version.
