Problem with syspkgs on 5.0.2 Patch and recent cvs update

[newhouse%rockhead.com@localhost (Paul Newhouse)]

Running NetBSD 5.0.2 Patch

This script probably isn't the most efficient but, it used to work.  I haven't 
built a kernel for couple of weeks but, something seems broken?  Clues 
appreciated.

TIA,
Paul
