GHCi runtime linker: fatal error: I found a duplicate definition for symbol r1p_closure whilst processing object file /grp/haskell/lib/ghc-5.02.2/HSHaXml.o This could be caused by: * Loading two different object files which export the same symbol * Specifying the same object file twice on the GHCi command line * An incorrect `package.conf' entry, causing some object to be loaded twice. GHCi cannot safely continue in this situation. Exiting now. Sorry.

This bug was fixed in 5.02.3, I believe. Cheers, Simon
