Anyone help? I noticed several earlier threads on this subject, several
seemed to experience this problem only on amd64 (my platform) I'm on
6.1-stable

It is a 2-week old install, and I have always got this problem.  My i386
laptops on 6.1-stable fetch fine.

If I delete all files in /var/db/portsnap, it sucessfully downloads the 45MB
file again, then goes right back to this problem - could it be due to the
fact that 6.1 is now not the latest stable version?

Thanks,
Steve
