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.

After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: shine, ghcjs-prim
