Can any one help?!!

I'm facing a problem installing php-mysql-4.2.2-17 rpm on a redhat 9 OS, i've installed mysql-3.23.54a-11 , php-4.2.2-17 and glibc-2.3.2-11.9 RPMs which are required for the one i need.
Each time i get this error:
libmysqlclient.so.10 is needed by php-mysql-4.2.2-17
php = 4.2.2-17 is needed by php-mysql-4.2.2-17
I red about this and didn't find a solution.
