can't read "portname": no such variable

[Jeremy Huddleston]

Anyone have any clue where this is coming from?  I've seen it in  
multiple ports (db46, gmp, gperf, zlib).  I think I started seeing it  
after updating base last week... all of these ports use muniversal...  
maybe that's part of it... anyone have a clue?
