portupgrade fails to run or do anything

[Ron (Lists)]

I'm trying to upgrade my ports and I can't get portupgrade to do 
anything.  I type 'sudo portupgrade apache' (or any package) and all I 
get back is a command prompt.  No error or any other message.  
portversion seems to work correctly, showing my out of date ports, etc.

Running portupgrade with -F doesn't help at all.  I've also noticed 
that tab-expansion isn't working like it used to on the port names, so 
that makes me wonder if the database is screwed up.  I've tried running 
pkgdb and it just returns like portupgrade.  Running portsdb to try and 
rebuild the index doesn't help.

Any ideas?  I'm perplexed and Google is no help.

Thanks
