thunderbird error

[Sheremeta Alexandr]

configure: error: ./configure failed for js/src
configure: error: ./configure failed for mozilla
===>  Script "configure" failed unexpectedly.
Please report the problem to gecko at FreeBSD.org [maintainer] and attach the
"/usr/ports/mail/thunderbird3/work/comm-1.9.1/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`).
