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
