[Radiance-general] Where does bgraph look for .plt files?

[Vaib]

Sorry if I missed to mention, all the .plt files are present at
/usr/share/radiance/meta/
only, and I have set the MDIR environment variable (in both .profile, and
.bashrc) to the same path. I just crosschecked again. May be there is
something not working on my system. Or not a good day today. Thank you!
