This should do the trick: cabal install HTTP --reinstall
This is yet another instance of the common diamond dependency problem, where
two different versions of a package get pulled into a single build. The
solution is to wait till Cabal solves this properly, and reinstall offending
packages in the meantime (any package that is build against an out-of-date
package is a possible trigger of this problem).
