I think the problem is that GHCi doesn't respect #ifdef conditional compilation.
The HaXml package has modules with stuff like

    #if defined(__HBC__)
    import IOMisc
    #endif

which seems to confuse the interpreter (but not the compiler).  I've
also seen reports that recent versions of GHC don't grok lines like

    #if __GLASGOW_HASKELL__ <= 210
