Problem with building firefox

[Андрей Рекунов]

Hello!
I was trying to build and install firefox from ports, but get an error and
this message: "Please report the problem to gecko at FreeBSD.org [maintainer]
and attach the
"/usr/ports/www/firefox/work/mozilla-release/obj-i386-portbld-freebsd10.0/config.log""
My ports are updated with portsnap, and here is the log-file.
Thanks for attention!
