Error connecting python 2.6 with mySQL5 problem (import _mysql - ImportError: File not found)

I am getting the following error on a ASUS RT16 tomato VPN installation:

Traceback (most recent call last):
  File "tedlogdb.py", line 5, in <module>
    import MySQLdb
  File "/opt/lib/python2.6/site-packages/MySQLdb/__init__.py", line 19, in <module>
    import _mysql
ImportError: File not found

I installed Optware package Python2.6, py-mysql and mysql5 (Version 5.0.88).
I get no error using mysql (version 4.1.22) but I would really like to use mySQL5. So just switching the mysql packages introduced that error.
I would really appreciate any ides how to connect to mysql5 using python. Or any workarounds.
