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.

Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: manifold-random-0.5.0.2 (user goal)
[__1] trying: vector-space-0.16 (dependency of manifold-random)
[__2] trying: manifolds-0.5.0.2 (dependency of manifold-random)
[__3] next goal: spatial-rotations (dependency of manifolds)
[__3] rejecting: spatial-rotations-0.1.0.1 (conflict: vector-space==0.16,
spatial-rotations => vector-space>=0.12 && <0.15)
[__3] rejecting: spatial-rotations-0.1.0.0 (conflict: vector-space==0.16,
spatial-rotations => vector-space>=0.12 && <0.13)
[__3] fail (backjumping, conflict set: manifolds, spatial-rotations,
vector-space)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: manifolds, manifold-random, base,
vector-space, spatial-rotations
