# Various Swift components require linking against `curses`; Gentoo doesn't
# `curses` as an alias for `ncurses`, so we have to link against `ncurses`
# explicitly. `ncurses` on Gentoo also doesn't expose the `curses` terminfo
# database interface (e.g., `set_curterm`, `del_curterm`, etc.), so we have to
# also explicitly link against `tinfo`.
