It's impractical to propagate ncurses — ncurses is very widely used and
this will cause "profile conflicts" if anyone tries to make a profile
that refers to multiple versions of ncurses.

Is there any way to make the built package refer explicitly to the
ncurses store directory, so that it can be a regular input?
