building php to have mysqli support...

hi... i'm trying to upgrade/install php-4.3.8 to include mysqli support. i'm running on a rh8.0 linux with mysql-4.x. i used the php-4.3.8 src rpm, and built using the following config ./configure --with-apxs2=/usr/sbin/apxs --with-config-file-path=/etc --with -mysql --with-mysqli=/usr/bin/mysql_config --with-ldap --with-pgsql i then used the following commands.. make clean ./configure make make install everything seemed to go ok, as everything appeared to run to completion and i didn't see any errors... i do appear to have created a new libphp4.so.... however, when i look in the php-dist.ini it has no mention of "mysqli"... so my question, have i screwed up somewhere?? or am i just looking for the php.ini file in the wrong location. has anybody managed to get php to work so you can actually use both mysql/mysqli??? pointers/criticisms/assistance is greatly appreciated! searching through google/php.net/etc.. hasn't turned up information on where i've gone wrong. thanks.. -bruce
