md5sum is missing, but not entirely

[perryh at pluto.rain.com]

Both the executable and the manpage for md5sum seem to be missing
from this 6.1-RELEASE system, making it difficult to check the
downloaded 6.2-RELEASE and FreeSBIE ISOs.  Isn't md5sum supposed
to be part of the base?

Meanwhile, "apropos md5" yields this line, among others

  gmd5sum(1), md5sum(1) - compute and check MD5 message digest

but "man md5sum" says

  No manual entry for md5sum

How did that line get into the apropos, when the corresponding
manpage is (apparently) not installed?
