Log Message:
+ Rename the "ncursesw" option to "wide-curses".  This \ 
should be supported
  under NetBSD-current without actually needing ncursesw.

+ Only make "wide-curses" an available option on platforms that have the
  necessary wide-character support.  It turns out NetBSD-3.x is not one
  of them.

+ Use a less patchy way to turn -ldb into -ldb3 by letting the wrappers
  do it.

+ Add full DESTDIR support.

Bump the PKGREVISION to 6.
