Hi,

I am trying to install a cabal package in a fresh, clean sandbox, but cabal fails with:

cabal: Could not resolve dependencies: Dependency tree exhaustively searched.

Update: It works when I manually install the package transformers-compat-0.3.2 first. - Does not work with transformers-0.2.2.1 - Works with transformers-0.3.0.0 (installed): $ cabal install transformers-compat-0.3.2 -f transformers3 $ cabal install --only-dependencies - Works with transformers-0.4.1.0: $ cabal install transformers-compat-0.3.2 $ cabal install --only-dependencies
