[Serusers] Error starting ser 0.9.3 with mysql

[leo at ltcjp.com]

Dear serusers,

BACKGROUND:
1) I have installed FC4 successfully. 
2) I have installed SER 0.9.3 WITHOUT mysql support successfully. I even
made phone calls.
3) I then ran the ser_mysql.sh script successfully. I see the 'ser'
database with its tables in mysql.
4) I them modifed ser.cfg to allow authentication.
5) I now get this message in the /var/log/messages file:

Jun 30 16:02:09 sip ser: ERROR: load_module: could not open module
</usr/local/lib/ser/modules/mysql.so>: libmysqlclient.so.12: cannot
open shared object file: No such file or directory 
Jun 30 16:02:09 sip ser: parse error (35,13-14): failed to load module 

QUESTION: Why do I get the above error message?

For reference the 1st 35 lines of my ser.cfg are enclosed. The above
seems to be complaining about line 35, line 14, and line 15
