It looks a bit like 'HaXml' has been updated after 'hxml' was built.
Try rebuilding 'hxml' against the 'HaXml' you've got installed.

FWIW I have the same problem - I can't use HaXml with ghci. So it's not just you. (-:
Indeed!
So I found my first bug in ghc... And now I'll dig into ghc bug reports to see if someone is working on the problem... This is going to be hard, but it's the way you start learning something....;-)
Thanks for your kind attention. Below the full error messages with the code producing them.

The code below works fine with Hugs: Main> :load xml.hs Main> main prova
Main>
If I try to compile it with ghc I get this:
