Thank you Philippe!  I specifically was looking for the commands to create the 
Debian binary packages which you gave me in your response back to me.  That 
sounds excellent Philippe.

I will definitely install your packages on Ubuntu 12.10 amd64 and let you know 
how it works out.

I have another question for you if you don't mind.  Do you use the Garbage 
Collection library or do you manually manage the Retain/Release counters along 
with auto release pools?  I have been doing some testing with manually managing 
them and it appears there is potential to have memory leaks from objects that 
either get allocated and never released properly or get allocated and released 
before the program is finished with them.

I have been overloading the dealloc methods to actually see objects getting 
reallocated when I release and the retain counter goes to zero and I can get 
pretty close (I think) to the right solution but it still is an area of concern 
for me.

Also, can you suggest a debug / analysis tool that works on Ubuntu / Debian 
Linux that I can use to watch for memory leaks.  Is GDB the tool?  I'm not 
exactly sure how to monitor & analyze for potential memory leaks and possible 
object references that get deallocated... Besides the program crashing :)

Thanks again.
