libvirt 1.1.3 doesn't compile on OS X 10.9 Mavericks. A bug report has
already been filed, but I was asked to write to this mailing list to
bring the matter to your attention.
https://bugzilla.redhat.com/show_bug.cgi?id=1023860
In that bug report it mentions that this was fixed, however the patch
linked to does not fix the problem.
