Setting up PHP and ODBC on Linux

Hello, as you may remember, some day ago, I asked how to develop on linux PHP pages accessing Mysql via ODBC (The reasons why I *have* to cope with this exact sub optimal set up are in the original message, no reason to repeat them here). I have installed all the UnixODBC rpms I could find ( I have RH 7.1); the iodbc packages on the openlinksw were not accessible. Now I have the following packages installed: [root@ari mweb] rpm -qa|egrep -i 'php|odbc|sql' php-4.0.4pl1-9 php-manual-4.0.4pl1-9 mysql-server-3.23.36-1 MyODBC-2.50.39-1 unixODBC-devel-2.0.7-1 asp2php-0.75.11-1 mysql-3.23.36-1 mysql-devel-3.23.36-1 php-mysql-4.0.4pl1-9 unixODBC-2.0.7-1 unixODBC-generic-2.0.7-1 mysqlclient9-3.23.22-4 unixODBC-mysql-2.0.7-1 However, I currently have PHP set up as pasted below (from phpinfo): that means I have to recompile it from scratch, doesn't it? If so, with which options? Is it enough to change --without-mysql to --with-mysql and add --with-odbc? Also, is it safer/worst/irrelevant/mandatory to erase the php rpm package before building it again from source?
