old automake removal

[Arthur Barlow]

Recently I did my usual ports upgrade by using portsnap .  The "pkg_version"
program shows that "automake-1.9" and "automake-1.10" and no longer current,
but for some reason the message "comparison failed" shows up when I check
the ports versions.  I've tried "pkgdb -u" to update the database, but I
still get this message each time I run pkg_version.  I've also done the
"portsclean -DD" program, but the warning is still there.  How do I clean
this up?
