during the boot sequence, I routinely see a "% fragmentation message".
It was my understanding that fragmentation doesn't occur on a Unix (er FreeBSD) box..
It seems that there is a concept of fragmentation from the above message, so, is there an "un-fragment" utility?

No there is not a defragmenting program. Fragmentation is not a problem it is part of the normal operation of the filesystem.
Data is stored in the filesystem in blocks, if a file does not have enough data to evenly fill all of its assigned blocks then the last block for the file is a fragment. The UFS filesystem will fill the fragment with new data when new data is added to the file.
Some filesystems used by a redmond based company do not attempt to fill existing fragments, but simply add new blocks to the file so that a file could have more than one fragmented block.
There are better descriptions of what is occurring in the archives, and presumably in textbooks that discuss filesystems.
