portupgrade problem

[Vince Hoffman]

Hi all,
 	Got a port upgrade problem here, ruby is dumping core during a 
portsdb -uU (and thus any time it tries to update the portsdb.
only noticed it today but i did upgrade ruby recently so i tried following 
the emergency recovery part in /usr/port/UPDATING and did
pkg_delete portupgrade-\*
pkg_delete -r ruby-\*
then cd /usr/ports/sysutils/portupgrade
make install clean

but no joy, i still get the same error 
---------cut portupgrade error test----------
