$MX/lib was not in LD_LIBRARY_PATH

That is interesting. On the head node,

 [/etc/]$ more mx.conf

But that is not there on the compute nodes. It must have been there
before the rebuild.

I was looking in /etc/* for things that were getting in my way
but not for things that were missing.

In any event, adding the $MX/lib to the relevant module takes care of
the issue.

Thank you...
