[Haskell-cafe] Cabal: top level dependency base -any

[Jacek Generowicz]

Hi,

Could anyone shed light on the meaning of this error message?

cabal: cannot configure xmonad-0.9.1 It requires base ==3.*
For the dependency on base ==3.* there are these packages:  
base-3.0.3.1 and
base-3.0.3.2. However none of them are available.
base-3.0.3.1 was excluded because of the top level dependency base -any
base-3.0.3.2 was excluded because of the top level dependency base -any


My guess is that "-any" would mean either that any version is  
acceptable (in which case should always work, including this time) or  
that "-any" means that any version is unacceptable, in which case it  
would never work, which is daft. So clearly I don't understand what it  
is trying to say.

Any hints?

Is this documented anywhere?

Thanks.
