MySQLdb module generating errors

[amaltasb]

I installed MySQLdb module on bsd and when I import I get the following
error...

Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "MySQLdb/__init__.py", line 27, in ?
import _mysql
ImportError: /usr/local/lib/liblthread.so.2: Undefined symbol
"_sched_yield"

Is any module missing ??

Thanks
