That gets me bsak to the original problem, which is:

[23 of 24] Compiling Haddock.Backends.Html ( src/Haddock/Backends/Html.hs, dist-install/build/haddock/haddock-tmp/Haddock/Backends/Html.o )

src/Haddock/Backends/Html.hs:1495:4:
    Ambiguous occurrence `maybeParen'
    It could refer to either `Haddock.Backends.Html.maybeParen', defined at src/Haddock/Backends/Html.hs:1462:0
                          or `GHC.maybeParen', imported from GHC at src/Haddock/Backends/Html.hs:42:0-39

src/Haddock/Backends/Html.hs:1511:4:
    Ambiguous occurrence `maybeParen'
    It could refer to either `Haddock.Backends.Html.maybeParen', defined at src/Haddock/Backends/Html.hs:1462:0
                          or `GHC.maybeParen', imported from GHC at src/Haddock/Backends/Html.hs:42:0-39

etc.
