Stale-Dependency problem after upgrade to 10

[David Southwell]

Can anyone tell me how to fix this one:

Stale dependency: bsdpan-Pod-Perldoc-3.15 -> perl-5.8.9_2 (lang/perl5.8):
can't convert nil into string


My update to 10 seems to be OK except for this..

I have tried pkgdb -fF
Tried pkg_deinstall bsdpan-Pod-Perldoc-3.15

Obviously I do not know what I am meant to do with this!!

THanks
in advance

David
