Is there a way to re-configure PHP 4.0.6 which is installed by default when installing RH7.2?

What I'd like to do is re-configure (using the --with-ibm-db2=/home/db2instr1/sqllib ) so that I can use DB2 UDB version 8.1 with PHP on an Apache server.

I really don't want to recompile PHP (after downloading PHP-4.3.4, doing the ./configure, make, and make install) since it doesn't appear to install "over" 4.0.6.

After downloading PHP-4.3.4, doing the configure (using --with-ibm-db2=/home/db2inst1/sqllib), the doing a make and a make install, on a VIRGIN installation of RH 7.2, when I run the phpinfo() function from a php page on the localhost, the PHP information webpage still displays PHP version 4.0.6 and the configure parameters show NO reference to the --with-ibm-db2.....

I've been trying to get IBM DB2 version 8.1 to work with PHP on Apache for 3 days and have tried all kindas of scenarios.

BTW - I'm a newbie of only 3 weeks with any use of Linux

TIA

I don't think this is feasible, unless you compile from source, or you user the SRPMS to rebuild the rpm, with your options.
