That didn't help.  I have found an error:
IOError: [Errno 13] Permission denied: 
it was in my main apache log, not the log for the virtual server I am 
running the command off of.  What I get permission denied to depends on 
what command I'm trying to run.  Sometimes it's a lock file.  If it's a 
group thing, I don't understand why--my perl scripts can run these 
commands fine, but my php cannot.  They both run from the same web 
server, so they'll both be running as the same user.
