Problem with ports

[Bob Myers]

I've started getting consistent port install/upgrade failures.   The 
"+CONTENTS" file of the package being installed isn't being installed into 
the /var/db/pkg/<port_name>/ directory and the port install fails trying to 
check it at that point.

Any ideas what could be causing this?   The ports directory has been freshly 
rebuilt via cvsup and I've ran all the tools I can think of (pkgdb, etc) 
trying to correct it.

Thanks...
