Please report the problem to gecko@FreeBSD.org [maintainer] and attach the
"/tmp/ports/usr/ports/mail/thunderbird/work/.build/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. a
/usr/local/sbin/pkg-static info -g -Ea).
