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<br>
*******************************************************************************<br>

Ok - this is a new test that got added to check for broken network that breaks MPI.<br>
<br>
Here is the check:<br>
<br>
Executing: ping -c 2 MarksMac-302.local<br>
<br>
The check says you have broken network settings. [as its not responding to ping.]<br>
<br>
Does MPI work fine on this box? You can try disabling this check (manually) - and do the build, and run<br>
<br>
Does MPI run fine?<br>
