No -- this is the correct mailing list for discussing all things ports
related. You might want to try contacting the port maintainer though --
to find the maintainer:

   % cd /usr/ports/misc/xdelta
   % make maintainer

One possibility is that this is related to the size of the files
you're dealing with.  Does xdelta function correctly for
smaller tarballs?  Is this on a 32 or a 64 bit system?

Could you try the misc/xdelta3 port which contains version 3.0t -- 
a late beta test version but pretty stable?

If this is a problem that you need a fast work-around to, check
out http://www.daemonology.net/bsdiff/ -- written by the chap who is 
currently FreeBSD security officer, and part of the base system
in FreeBSD.  See bsdiff(1) and bspatch(1).

	Cheers,
