neon28 fails, conflicts with neon26

[Eduardo Cerejo]

FreeBSD 7 stable

ports/UPDATING mentions this:

subversion now uses neon-0.28.x (www/neon28) port, and automatic
  portupgrade will fail because www/neon28 will conflict with installed
  www/neon26 port.

  You should upgrade neon library before subversion with the command:

	# portupgrade -o www/neon28 neon26

I did exactly that and It still fails:

** Command failed [exit code 1]: /usr/bin/script -qa /tmp/portupgrade.44225.0 env UPGRADE_TOOL=portupgrade UPGRADE_PORT=neon26-0.26.4_1 UPGRADE_PORT_VER=0.26.4_1 make reinstall
