As always, thanks for the insights Glen -- that was the piece I was
looking for.  :-)

John Mehr might be able to comment on this, but here's an idea (stated
with zero knowledge of, well, pretty much anything!):

Depending on what all goes on within svnup (and what the SVN protocol
offers), is it possible for svnup to pull down a revision number and
store it somewhere (ex. /var/db/svnup-revision would contain rXXXXXX),
then as part of the svnup package/suite, have a shell script called
"svnversion" that simply provides the content of that file?

That looks like it'd be compatible with sys/conf/, which

 91 for dir in /bin /usr/bin /usr/local/bin; do
 92         if [ -x "${dir}/svnversion" ] ; then
 93                 svnversion=${dir}/svnversion
 94                 break
 95         fi
 96 done
106 if [ -n "$svnversion" ] ; then
107         echo "$svnversion"
108         svn=`cd ${SYSDIR} && $svnversion`
109         case "$svn" in
110         [0-9]*) svn=" r${svn}" ;;
111         *)      unset svn ;;
112         esac
113 fi

Naturally the svnup port would need to have a CONFLICTS line added,
since having both svnup and subversion installed on the same machine
would result in a /usr/local/bin/svnversion conflict.
