cabal: cannot configure SybWidget-0.5.4. It requires base >=4.1.0 && <4.3.0
For the dependency on base >=4.1.0 && <4.3.0 there are these packages:
base-4.1.0.0, base-4.2.0.0, base-4.2.0.1 and base-4.2.0.2. However none of
them are available.

base-4.2.0.1 was excluded because of the top level dependency base -any
