Ok - I can confirm that even with installed Trilinos I do still get these
collisions and I verified that there is going to be no way to compile
against NOX without using -DHAVE_CONFIG_H.... even with an installed
Trilinos.
So.... I think the best option is to prefix all of our #defines with
LIBMESH_.
Ben... since it sounds like you have a handle on the situation... you have
the greenlight from me ;-) If you don't do it, I'll probably do it pretty
soon. Just so it's clear, it's not just HAVE_MPI... it's quite a few
different ones... that was just a representative one... so they really do
all need to get prefixed.
