Please refer to old PR (basically the same problem -
why do you create new PRs for the same problem ?).

Yesterday I built libreoffice successfully on
FreeBSD 9.0-RELEASE-p3 #0.

There is a build log that documents that your "fix" by removing
boost-* libs is not needed, at least on this FB release.
Read the logs and comments - it is all there.
