[Haskell-cafe] broken on build encoding

Hi, cafe,

   I always get the following build failure when I try to install encoding:

 Configuring encoding-0.6.4...
Warning: This package indirectly depends on multiple versions of the same
package. This is highly likely to cause a compile failure.

I manually installed a ghc-6.12.3, a ubuntu ghc-6.12.1, all the same?

anybody can provide helps? thanks
