You can usually[1] get a root shell on systems that use sudo by issuing 
"sudo -s". Once there, you can source in the usual way.

"source" is a shell built-in, so doesn't exist as a binary on the path, 
and thus won't work with sudo, as you've discovered.


1. This is security-policy dependent, but generally works unless you've 
explicitly configured it otherwise.
