The latest release of setuptools will automatially detect that there is a 
.dll present, and add it to the native_libraries.txt file for 
you.  However, if you want to be explicit, just add

      eager_resources=['pysqlite2/sqlite3.dll']

to your setup() arguments.

I actually added the DLL detection specifically because of 
pysqlite.  :)  Mainly, it made me realize that I ought to just detect dll, 
so, pyd, and dylib files automatically, so that eager_resources is only 
needed for *data* files that may be used by C extensions.
