Unable to load dynamic library / mysql.so

[Zbigniew Szalbot]

Hello,

I got a php warning and I am not sure what would be the best way to
deal with it. I'd like to be able to load the dynamic extension as
without it database back-end sites won't work. Will it help to force
upgrade of php4 and php4-extensions (portupgrade -f)?

php -v
PHP Warning:  Unknown(): Unable to load dynamic library
'/usr/local/lib/php/20020429/mysql.so' - Shared object
"libmysqlclient.so.15" not found, required by
"mysql.so" in Unknown on line 0

mysql --version
mysql  Ver 14.14 Distrib 5.1.21-beta, for portbld-freebsd6.2 (i386) using  5.0

Many thanks for your suggestions!
