i've just get the git clone of : git://github.com/forhappy/cpy-leveldb.git
i'm on ubuntu 11.10
here are my problem :

in /tmp/cpy-leveldb :
cd snappy
but no ./configure file need to ./autogen.sh first

after done everything in the README.TXT
all compile installation ok

But when try python and test leveldb i've got that :
the import of leveldb ok

Python 2.7.2+ (default, Oct 4 2011, 20:03:08)
[GCC 4.6.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
import leveldb
db = leveldb.LevelDB("/tmp/leveldb")
Traceback (most recent call last):
File "", line 1, in
AttributeError: 'module' object has no attribute 'LevelDB'

thks for help

I found that leveldb_options_set_filter_policy was not called in LevelDB_init . Does any reason to do so ?

Here's an error I get when I come to python setup.py build. Any ideas of how to resolve it? I use a Fedora system, leveldb and snappy compiled and installed fine.
