I've found that the fun->pdf link in www.haskell.org/libraries/ broken, does anyone know whether there is an update of it? or any other library that equivalent?

Try looking for it in

http://www.archive.org/

I recovered some of Jan's other libraries using the Wayback Machine.

If you do this, please place a copy on your own page so that it's preserved for others. Even better, arrange for a "(now available at...)" link to be added to the haskell.org page. We can't rely on the Wayback Machine being there forever. Thanks. --KW 8-)
