Summary: rt segfaults when BRLCAD_ROOT is not set

Initial Comment:
It should print an error only and not print an error
and segfault:

Shader "platic"... Unable to locate where BRL-CAD 7.8.2
is installed while searching:
        BRLCAD_ROOT environment variable
        BRLCAD_ROOT compile-time path [/usr/brlcad]
        run-time path identification [UNKNOWN]
        current directory

This version of BRL-CAD was compiled to be installed at:
        /usr/brlcad

You may specify where to locate BRL-CAD by setting the
BRLCAD_ROOT
environment variable.  For example:

for csh/tcsh users:
        setenv BRLCAD_ROOT /path/to/brlcad
for sh/bash users:
        BRLCAD_ROOT=/path/to/brlcad ; export BRLCAD_ROOT

Unable to find '/lib/libplatic.so' within the BRL-CAD
software installation.
This copy of BRL-CAD may not be properly installed.

What install setup did you use to provoke this error?  Were you installed
in another directory than /usr/brlcad?
