Just a thought

I would probably use sets and see if the value that you are looking for
using the
union of the two lists. (Yes it won't scale to really big lists)
for instance if you do the following
set1 = set(list1)
set2 = set(list2)


you can then do a single check

if "XXX%d" % i not in set1.union(set2):  # or set1 | set2
 # do something

I am not sure exactly what you are looking for but
I assume you are using windows, so I would suggest you make sure you
have Mark Hammonds win32all
(http://www.python.net/crew/mhammond/win32/) installed
and have a look at the demos there.

You should be linking against a dynamic version of libjpeg rather than
the static version.  ie libjpeg.so   Looks like you have locally
installed libjpeg but only built a static version.
