It will be socker_wrapper, I think we now have code to stop our tests
leaking out.  
If you want access to the real internet, remove the socket wrapper
environment variables or otherwise disable it. 
But also, don't do that.  At least in the past, the autobuild host does
not permit outbound access, so you will need to work with the
sysadmins. 
The preferred pattern from our C model of software development is to
encode dependencies at image generation time, and manually install on
the autobuild host.
