It's there for packages that need only rudimentary curses support (BSD
baseline) as opposed to "ncurses-compatible" support. It basically looks to
see if /usr/include/[n]curses.h exists, and only if not, includes
devel/ncurses/buildlink3.mk to provide a backing implementation.
www/lynx uses it, for instance.

Your implied connotation is that the "needed curses libraries" might or
might not be in the base system because of packaging, such as with
pkgsrc-based Linux. :) Perhaps curses.buildlink3.mk should heed
PREFER_PKGSRC.ncurses to address this issue?
