I think the answer is given at:
http://stackoverflow.com/questions/7339635/ambiguous-module-name-prelude
HXQ is not updated since 2011; the package haskell98 should be removed

Also it is recommended to install things into project specific sandboxes
rather than globally.
E.g.
mkdir myProj
cd myProj
cabal sandbox init
cabal install hxq
