[Haskell-cafe] errors while installing yesod 0.8

[Michael Litchard]

Following the install trail I run into this problem

mlitchard at apotheosis:~$ cab install JSONb-1.0.2

Text/JSONb/Decode.hs:56:33:
    Ambiguous occurrence `number'
    It could refer to either `Text.JSONb.Decode.number', defined at
Text/JSONb/Decode.hs:118:0
                          or `Attoparsec.number', imported from
Data.Attoparsec.Char8 at Text/JSONb/Decode.hs:25:0-52
cabal: Error: some packages failed to install:
JSONb-1.0.2 failed during the building phase. The exception was:
ExitFailure 1


How do I clear up this ambiguity?
