I agree, and it is indeed my doing. The problem began with trouble
understanding the freebsd-update script. This has now been resolved.

The system is of the Intel Xeon 5000X variety

At 8.1-RELEASE, I had used portsnap only, and had not touched the kernel
or the base system sources. I was under the impression that there would
be no linking issues if only the ports collection was updated. Philip is
right, my ports and system were out of sync.
