Warning: The install command is a part of the legacy v1 style of cabal usage.
Please switch to using either the new project style and the new-install
command or the legacy v1-install alias as new-style projects will become the
default in the next version of cabal-install. Please file a bug if you cannot
replicate a working v1- use case with the new-style commands.

[__1] rejecting: sdl2-mixer-1.1.0, sdl2-mixer-0.1 (conflict: pkg-config
package SDL2_mixer>=2.0.0, not found in the pkg-config database)
[__1] fail (backjumping, conflict set: grid-proto, sdl2-mixer)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: sdl2-mixer, grid-proto
