I am trying to install the Haskell Crypto package using Cabal. I have a problem when using Cabal. I have installed NewBinary-0.1 but when trying to configure the Crypto library using Setup.exe configure --prefix=h:\NewHaXml I receive the message: Configuring Crypto-2.0.3... configure: Dependency base-any: using base-1.0 configure: Dependency mtl-any: using mtl-1.0 configure: Dependency QuickCheck-any: using QuickCheck-1.0 configure: Dependency HUnit-any: using HUnit-1.1 Setup.exe: cannot satisfy dependency NewBinary-any This suggests that a NewBinary package does not exist but ghc-pkg list returns: h:\Cfgs\ie\AppData\ghc\i386-mingw32-6.4\package.conf: Cabal-1.1.4, NewBinary-0.1 Any suggestions?
