I installed HaXml 1.08 newly under ghc 6 and get the following error when using ghci -package HaXml:

GHCi runtime linker: fatal error: I found a duplicate definition for symbol TextziPrettyPrintziHughesPJ_zdzpzd_entry whilst processing object file /usr/local/lib/ghc-6.0/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.

The cause is a simple configuration problem. HaXml checks for ghc version >= 504 and deletes the extra copy of Text.PrettyPrint.HughesPJ. Unfortunately, with the change in version numbering format, 60 < 504, so the test fails. You need to apply the following patch to the HaXml configure script.
