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.

cabal: Could not resolve dependencies:
[__0] trying: gi-cairo-again-1.16.0 (user goal)
[__1] next goal: cairo-core (dependency of gi-cairo-again)
[__1] rejecting: cairo-core-1.16.3 (conflict: pkg-config package cairo-any,
not found in the pkg-config database)
[__1] fail (backjumping, conflict set: cairo-core, gi-cairo-again)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: cairo-core, gi-cairo-again
