[pysqlite] test.test() error on osX using python2.5.4

Hello everybody,

I just installed pysqlite-2.5.5 withour error (for the first time).

Trying the test.test() routine I got 2 Errors.

The first error is declared as everything is fine, it's just a mac (http://osdir.com/ml/python.db.pysqlite.user/2008-05/msg00003.html 
)
So I don't worry much about it.

But what can I do against the second Failure (FAIL:  
CheckSetIsolationLevel) ?

here is the output:
