can someone please fix mergemaster and bind?

It is painful to have my setup destroyed after every mergemaster. 
Anyone with bind9 setup and running should not try this without first
backing up their /var/named/etc/namedb directory:

mergemaster
...
  *** There is no installed version of
./var/named/etc/namedb/PROTO.localhost.rev

  Use 'd' to delete the temporary
./var/named/etc/namedb/PROTO.localhost.rev
  Use 'i' to install the temporary
./var/named/etc/namedb/PROTO.localhost.rev

  Default is to leave the temporary file to deal with by hand

How should I deal with this? [Leave it for later]
i

   *** ./var/named/etc/namedb/PROTO.localhost.rev installed successfully


  *** There is no installed version of
./var/named/etc/namedb/PROTO.localhost-v6.rev

run mergemaster again and it does the same thing!!!  Fix my named.conf
and it is deleted again with mergemaster.
