>Description:
portmaster bombs out late in the process because it doesn't check for root-based credentials before it tries to update packages. Discovered this by accident because I accidentally forgot to run portmaster with sudo.
>How-To-Repeat:
sudo -u nobody portmaster -a
>Fix:
Check for root privs sooner.
