Proxy problem

[notbot]

Hi

I hope you can help. I am trying to get MacPorts working from a  
University with a proxy server.

When I last did this there was no problem and no config required, but  
that was with OSX10.5, this time it is with OSX 10.6.4.

Selfupdate works fine, but when attempting to fetch a port it fails  
with a 407 error.

Is there some config required to macports.conf?

Many thanks
