Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: htalkat-0.1.2.2 (user goal)
[__1] rejecting: htalkat:+curses (conflict: pkg-config package ncursesw-any,
not found in the pkg-config database)
[__1] rejecting: htalkat:-curses (manual flag can only be changed explicitly)
[__1] fail (backjumping, conflict set: htalkat, htalkat:curses)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: htalkat, htalkat:curses
