I logged on as myself, su'd to root, then su'd again to the apache 
user.  Then I said

     /usr/bin/svn ls file:///usr/local/svnroot/repos/MyRepo

... and got back:

     branches/
     tags/
     trunk/

... which is exactly what is supposed to be there.

I guess I don't really know how to replicate apache's environment any 
better than that.

On the other hand I know that su doesn't typically build a whole new 
environment for the user being su'd to.

I also believe that httpd does its own little tweaking of the environment 
here and there, so that the environment one sees when logging on as the 
apache user isn't necessarily all that's there.

Is there a php statement I can execute, something like a var_dump, that 
will show me the environment that chora is trying to operate in, hopefully 
with some newlines after each environment variable so I can see what's going on?
