Missing symbol when loading cbits in ghci

[Don Stewart]

Anyone seen this?

    $ ghci A.hs
    Prelude Main> main
    <interactive>:
    /home/dons/.cabal/lib/download-0.3/ghc-6.8.2/HSdownload-0.3.o:
    unknown symbol `stat64'
    ghc-6.8.2: unable to load package `download-0.3'

I can compile and link code against HSdownload just fine,
but loading in ghci fails with state64 undefined (a kernel symbol).

To reproduce:

    $ cabal update
    $ cabal install download
    $ ghci
    Prelude> :m + Network.Download
    Prelude Network.Download> openURI "http://haskell.org"

    <interactive>:
    /home/dons/.cabal/lib/download-0.3/ghc-6.8.2/HSdownload-0.3.o: unknown
    symbol `stat64'
    ghc-6.8.2: unable to load package `download-0.3'

Is this something that ghci should know about on linux? Or can anyone
think of another reason why ghci can't see stat64?
