My apologies.  I should have been significantly clearer in what I was 
trying for there.  :)

(adding the libvirt devel mailing list back in, due to relevance)

Tried compiling libvirt on OS X, which errored on this piece of IPv6 code:

  http://www.redhat.com/archives/libvir-list/2010-September/msg00243.html

The message I quoted to Eric above, which you've then looked at, was 
danpb wondering whether we should be using gnulib to avoid the 
portability problem.

This stuff is outside my area of expertise though. :)
