Ah, ok. I was looking at a different wiki page. The HOWTO get started
with Hall-D Software
<http://www.jlab.org/Hall-D/software/wiki/index.php/Getting_started_with_GlueX_Software>
implied mcsmear was for tracking chambers. HOWTO get started quickly
with Hall-D Software
<http://www.jlab.org/Hall-D/software/wiki/index.php/Quick_Start_Guide_to_building_GlueX_Software>
is the one I should have followed.
Thanks,
Blake
