help me error in install this program

[паша Савельев]

checking Ant lib directory... configure: error: Ant libraries not found!
===>  Script "configure" failed unexpectedly.
Please report the problem to openoffice at FreeBSD.org [maintainer] and 
attach
the
"/usr/ports/editors/openoffice.org-2.0/work/OOC680_m7/config_office/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`).
*** Error code 1

Stop in /usr/ports/editors/openoffice.org-2.0.
