problems to enable pd_mysql/mysqli

Hi List, have a little Problem to enable pdo_mysql/mysqli in current php 5.2.6 installed ist Mysql 5.0.67 MySQL-server-5.0.67-0 MySQL-shared-compat-5.0.67-0 MySQL-devel-5.0.67-0 MySQL-shared-5.0.67-0 MySQL-client-5.0.67-0 Configurer switch for mysql is: --with-mysql=shared,/usr . --with-mysqli=shared,/usr/bin/mysql_config \ . --with-pdo-mysql=shared,/usr \ Compiling stops with error: gcc: /usr/lib/mysql/libmysqlclient.so: No such file or directory libmysqlclient.so is located in /usr/lib/ but /usr/bin/mysql_config shows: Options:

       --cflags        [-I/usr/include/mysql  -I/usr/local/include -L/usr/local/lib -fno-strength-reduce]
       --include        [-I/usr/include/mysql]
       --libs          [-rdynamic -L/usr/lib/mysql -lmysqlclient -lz -lcrypt -lnsl -lm -lc -lnss_files -lnss_dns -lresolv -lc -lnss_files -lnss_dns -lresolv -lmygcc]
       --libs_r        [-rdynamic -L/usr/lib/mysql -lmysqlclient_r -lz -lpthread -lcrypt -lnsl -lm -lpthread -lc -lnss_files -lnss_dns -lresolv -lc -lnss_files -lnss_dns  -lresolv -lmygcc]
       --socket         [/var/lib/mysql/mysql.sock]
       --port           [0]
       --version        [5.0.67]
       --libmysqld-libs [-rdynamic -L/usr/lib/mysql -lmysqld -lz -lpthread -lcrypt -lnsl -lm -lpthread -lc -lnss_files -lnss_dns -lresolv -lc -lnss_files -lnss_dns -lresolv -lrt  -lmygcc]

I could copy libmysqlclient.so from /usr/lib/ to /usr/lib/mysql/ to compile successfully but its not a clean solution. mysql rpms are original from mysql.com What goes wrong? Thank you Andre
