Thanks for the info - what file do I need to distribute along with .py file ? 
where do I find it ? and where does it need to go ? Can I put a compiled file 
into the same directory as my .py file !?

I just discovered (on my linux box)
/tmp/haase/python24_intermediate/compiler_cae5f1e251cd037a19f0234c558d6f0e 
!?

Thanks,
Sebastian Haase
