OpenOffice.org
From FreeBSDwiki
A full office suite, not unlike Microsoft Office, but based on Sun's StarOffice suite, which was released as an open-source licensed product (in the StarOffice version 5). Available for Windows, Linux, Solaris and BSDs, you may see it abreviated as "OOo".
Requires java, so the ports install takes a long time and you have to do all the downloading and unzipping etc that the Java page mentions. Alternately, you can get pre-built binaries for FreeBSD 5.4 or 6 -RELEASE at Good Day for both the older 1.2 or newer 2.0 OOo releases.
Be sure to cvsup to the latest ports and portupgrade any old ports if you're going to be installing the 2.0-devel version of OOo; it'll save you a lot of time.
