PHP startup error in Apache error log

[Jose Borquez]

I am running FreeBSD 5.4 with Apache+mod_ssl 1.3.34, 
mysql-server-5.0.16, mysql-client-5.0.16, php5-5.1.1, and 
php5-mysql-5.1.1.  I see the following error messages every time I 
attempt to access a php page:

PHP Warning:  PHP Startup: Unable to load dynamic library 
'/usr/local/lib/php/20
050922-debug/mysql.so' - Cannot open 
"/usr/local/lib/php/20050922-debug/mys
ql.so" in Unknown on line 0

Could someone please let me know if I have configured something 
improperly or what I need to look for?

Thanks in advance,
