FreeBSD ports via authenticated proxy firewall

If you need to use the FreeBSD ports system from behind a proxy, you may have found these articles outlining how to make fetch(1) work over a proxy, and how to replace fetch(1) with wget(1). What you might be interested in if you are using FreeBSD 4.10 (I think 4.x since 4.7) with an authenticated proxy server (that requires you to give a name and password to access web sites) is that you need to add DISABLE_SIZE=1 to /etc/make.conf under the FETCH_CMD line to make these versions of FreeBSD ports work with wget.
Hope that helps someone.
