Comment:

 ncurses doesn't provide an `ncurses-config` program; they only provide one
 with a version number in it. So if we change "ncurses5-config" to
 "ncurses6-config", this is just going to break again when ncurses 7 is
 released. So let's fix it right, by using `pkg-config`, since the pkg-
 config file doesn't have a version number in it. Patch attached. @mjhsieh,
 if there are no objections, I'm happy to commit it.
