===>  Script "configure" failed unexpectedly.
Please report the problem to x11 at FreeBSD.org [maintainer] and attach the
"/usr/ports/x11/libX11/work/libX11-1.4.4/config.log" including the output of
the failure of your make command. Also, it might be a good idea to provide
an overview of all packages installed on your system (e.g. an `ls
/var/db/pkg`).
