Please run the gnomelogalyzer, available from
"http://www.freebsd.org/gnome/gnomelogalyzer.sh", which will diagnose the
problem and suggest a solution. If - and only if - the gnomelogalyzer cannot
solve the problem, report the build failure to the FreeBSD GNOME team at
gnome@FreeBSD.org, and attach (a)
"/usr/ports/textproc/libxml2/work/libxml2-2.7.8/config.log", (b) the output
of the failed make command, and (c) the gnomelogalyzer output. Also, it might
be a good idea to provide an overview of all packages installed on your system
(i.e. an `ls /var/db/pkg`). Put your attachment up on any website,
copy-and-paste into http://freebsd-gnome.pastebin.com, or use send-pr(1) with
the attachment. Try to avoid sending any attachments to the mailing list
(gnome@FreeBSD.org), because attachments sent to FreeBSD mailing lists are
usually discarded by the mailing list software.
