Message when updating ports

[Leslie Jensen]

This message has been on my screen almost every time I update a port for 
the last week.


===>>> Updating package dependency entry for each dependent port
         ===>>> @comment MD5:e417e49fb3570516da077756fc1e7df9 is listed 
as a dependency
         ===>>> but there is no installed version

I have done checks like pkgdb -F, portsclean and so on.

Can anyone tell me whats wrong?

Thanks

Leslie
