[Haskell-beginners] Cabal error

I get the following Cabal install error: C:\Users\haskell>cabal install buildwrapper Resolving dependencies... Configuring regex-tdfa-1.1.8... Warning: This package indirectly depends on multiple versions of the same package. This is highly likely to cause a compile failure. If true, doesn't this mean that the regex-tdfa package has misconfigured dependencies? -------------------------------------------
