Invalid path for portupgrade ftp.FreeBSD.orgpub

[Gianni Doe]

I'm upgrading a system from 6.4 to 7.1 and rebuilding all the ports.
I'd rather use packages where present to speed things up a bit so I'm  
using:
# portupgrade -faP

The problem is that it never finds the packages as the URL is invalid,  
there seems to be a missing slash between in ftp.FreeBSD.orgpub

fetch: ftp://ftp.FreeBSD.orgpub/FreeBSD/ports/i386/packages-7-stable/All/djbdns-1.05_12.tbz 
: No address record
** The command returned a non-zero exit status: 1

fetch: ftp://ftp.FreeBSD.orgpub/FreeBSD/ports/i386/packages-7-stable/All/djbdns-1.05_12.tgz 
: No address record

I've got the latest portupgrade.
portupgrade-2.4.6,2

Is there somewhere I can specify/fix this path?
