cabal: cannot configure filestore-0.2. It requires parsec ==2.*
For the dependency on parsec ==2.* there are these packages: parsec-2.0,
parsec-2.1.0.0 and parsec-2.1.0.1. However none of them are available.
parsec-2.0 was excluded because orchid-0.0.8 requires parsec ==3.0.*
parsec-2.1.0.0 was excluded because orchid-0.0.8 requires parsec ==3.0.*
parsec-2.1.0.1 was excluded because orchid-0.0.8 requires parsec ==3.0.*
