upgrade php 5.2.6 -> 5.2.8 mysql problems!

Hello everybody, I am trying to update php 5.2.6 to 5.2.8 on a test system. Somehow it can not find the working mysql installation. With 5.2.6 I everything is fine. Here is the configure command that is pretty much the same as in 5.2.6: './configure' '--enable-fastcgi' '--with-mysql' '--prefix=/usr/local/php' '--with-apxs2=/usr/local/apache2/bin/apxs' '--enable-mbstring' '--with-pdo-mysql=/usr/local/mysql/' '--with-mysql-sock=/tmp' '--enable-soap' '--with-zlib' '--with-freetype-dir=/usr/local/lib' '--with-gd' '--with-jpeg-dir=/usr' '--with-png-dir=/usr/lib' '--enable-exif' '--enable-cli' PHP returns: checking for MySQL UNIX socket location... /tmp configure: error: Cannot find MySQL header files under yes. Note that the MySQL client library is not bundled anymore! According to a google search mysql-dev is not installed. So I tried to get it with yast on the suse 11.0 server. No luck. So I got it via a rpm. That returns: rpm -i mysql-devel.rpm error: Failed dependencies:

Something must be wrong. I can't believe that there is so much change necessary for such a minur upgrade. Any ideas? Thank you for any help, Merlin
