Make sure that if we ask for the 'none' component (which is not a 'real' component, but a component in crs/base) then we do not fail out of the box when using tools. We check for the {{{OPAL_ERR_NOT_FOUND}}} error.
Also make sure that component_open() returns {{{OPAL_ERR_NOT_FOUND}}} when it cannot find a value instead of {{{OPAL_ERROR}}} which means something quite a bit different.
C/R is working but the tools still print the warning below everytime they are ran:
{{{
--------------------------------------------------------------------------
A requested component was not found, or was unable to be opened. This
means that this component is either not installed or is unable to be
used on your system (e.g., sometimes this means that shared libraries
that the component requires are unable to be found/loaded). Note that
Open MPI stopped checking at the first component that it did not find.
Host: odin.cs.indiana.edu
Framework: crs
Component: none
--------------------------------------------------------------------------
}}}
I'll have to figure out a work around for this warning (maybe work on the {{{MCA_NULL}}} Ticket #1291).
