Resolving dependencies...
Error: cabal: Could not resolve dependencies:
[__0] trying: Raincat-1.2.3 (user goal)
[__1] next goal: sdl2-mixer (dependency of Raincat)
[__1] rejecting: sdl2-mixer-1.2.0.0 (conflict: pkg-config package
SDL2_mixer>=2.0.0, not found in the pkg-config database)
[__1] rejecting: sdl2-mixer-1.1.0 (conflict: Raincat => sdl2-mixer^>=1.2)
[__1] skipping: sdl2-mixer-0.1 (has the same characteristics that caused the
previous version to fail: excluded by constraint '^>=1.2' from 'Raincat')
[__1] fail (backjumping, conflict set: Raincat, sdl2-mixer)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: Raincat, sdl2-mixer
