Frank,

Thank you for looking into this, it is very much appreciated.

While the patch "looks" like it should be getting executed, I'm not 
convinced that it is as I added some addition output and it was not 
being generated and I'm still tring to resolve this with the sysadmin. I 
did copy the svn changset verbatim into my code which was when I added 
more prints and discovered this issue on my end. So, I'm not sure we are 
actually executing the patched code in spite of what my attempts to 
verify it said.

I'll let you know one way or the other once I get a better handle on 
this here.

Thanks again for the follow up.
