I don't see any errors there. The extract of the log that you quoted
seems to just be configure finding out that your platform doesn't have
setproctitle(), which is hardly surprising on Linux (it's a BSD-ism).
In any case that would have nothing to do with libxml or libxslt.
What actual problem are you having?
