Seems to be on all FreeBSD machines I have access to, which is three.
 FreeBSD 4.6-STABLE (2)
 FreeBSD 4.7-PRERELEASE

I assume the FreeBSD version.

$ mv --version
usage: mv [-f | -i | -n] [-v] source target
       mv [-f | -i | -n] [-v] source ... directory

"." is on /home and /tmp is on another partition (or in another case, /home
is nfs mounted).

Creating the file in /tmp is setting a guid "wheel" which I am not part of.
 So the file is copied, and then the chgrp fails.

Nope, not running root.  the above case is not on the nfs mounted /home, of
course.
