gnome-vfs-2.16.3 -> stale dependency question

[Vizion]

running pkgdb -F 
I am getting
**Stale lock file was found. Removed
Stale dependency: gnome-vfs-2.16.3 ->geimdal-0.7.2_2 (security/heimdal
Install stale dependency?


What is the appropriate response?
Yes would result in an attempt to install heimdal which is not practical due to conflict with krb.
No is a prompt for a new dependency.. 
I know not how to respond to that one.
Until this is sorted portupgrade -a does not run
Advice would be appreciated.

I looked at UPDATING but if there is anything I must have missed it.

Thanks
David
