still there are changes

i hope one day it will be possible to deploy app over net 
by just unpacking tar ball done at test machine on production 
one, though this seems questionable:

it might be for some packages relying on 3rd party libs such as lxml, root 
account had to be provided. 
or may be there are some acceptable hacks similar to patching 
RPATH on bin's?
