[Zope-DB] ZMySQLDA on solaris10

[Comunian Alessandro]

Dear all,
Since some day I am trying to install ZMySQLDA on a sunblade1500 (Solaris10) 
workstation, but running my zope instance in debug mode "off" I always get 
errors like (from .../log/event.log):

------
2007-02-22T12:11:20 ERROR Zope Couldn't install ZMySQLDA
Traceback (most recent call last):

ImportError: ld.so.1: python: fatal: relocation error: 
file /home/wwhypda/plone/instance_test01/lib/python/_mysql.so: symbol 
mysql_errno: referenced symbol not found
------

I have:

- MySQL 5.0.27 from binaries for solaris10
- Plone version installed: 2.5.2
- MySQL-python-1.2.1_p2 installed using the Python version that comes with 
Plone (2.4.4)
- ZMySQLDA 2.0.8 (also tried 2.0.9b3)

Have you some suggestion, please?
Thank you in advance!
Bests,

Alessandro
