Exception: Your hostname will not work with MPI, perhaps you have VPN running whose network settings may not play well with MPI or your network is misconfigured

Ok - this is a new test that got added to check for broken network that breaks MPI.

Here is the check:

Executing: ping -c 2 MarksMac-302.local

The check says you have broken network settings. [as its not responding to ping.]

Does MPI work fine on this box? You can try disabling this check (manually) - and do the build, and run

Does MPI run fine?
