Works on my traces on Windows, could it be libxml related?

Yes
>(TCP/SCTP Port 3868 seems to be the new RFC assigned port , see RFC 3588

The port used is configurable so this shoulden't be a big problem.

This is a licencing issue i belive, note however that libxml is NOT needed to dissect Diameter
messages, actually the value strings containing Diameter "translations" is more up to date than the
XML dictionary is. The only reason for using libxml is if you have a dictionary for private AVP:s I think.
You do get a warning that libxml is not present when loding a Diameter trace isn't that enough?
