[Haskell-beginners] Ambiguous module name `Prelude': it was found in multiple packages (trying to install HXQ)

[Stanislaw Findeisen]

Hi!

I am trying to install HXQ: https://hackage.haskell.org/package/HXQ . 
But somehow it doesn't work:

$ cabal install hxq
Resolving dependencies...
Configuring HXQ-0.19.0...
Building HXQ-0.19.0...
Failed to install HXQ-0.19.0
Build log ( /home/ct/.cabal/logs/HXQ-0.19.0.log ):
Configuring HXQ-0.19.0...
Building HXQ-0.19.0...
Preprocessing library HXQ-0.19.0...

src/Text/XML/HXQ/XQuery.hs:1:1:
     Ambiguous module name `Prelude':
       it was found in multiple packages: base haskell98-2.0.0.2
cabal: Error: some packages failed to install:
HXQ-0.19.0 failed during the building phase. The exception was:
ExitFailure 1

Why?

Thanks!
