Data.ByteString.Lazy defines ByteString as a type synonym, and then uses that in instances, which isn't permitted by Haskell 98.
I recently sent some patches to the fps package, to enable it to build with nhc98. They simply change these instance decls to use the original type name rather than the synonym. (The original name was even in scope, so there was no compelling reason to use the synonym in the first place.) Btw, my patches have not yet appeared in the official fps repo. I think dons was going to be responsible for pushing them into base at the next merge point between fps and base. Regards, Malcolm
