The solution was that I needed to modify my open_basedir line in 
http.conf for the virtual host and include /usr/bin.  After I did this 
for http, I struggled with why it wasn't working still reliably.  Dur!  
I also had to make this change in the SSL config for the site.

I think it is amazing that after being completely frustrated and after I 
post to the list, minutes later I find the solution.  Oh well......
