php.ini doesn't get loaded

Hello, I'm trying to compile PHP 5.2.3 on CentOS with the following configure: './configure' '--prefix=/usr/local/php' '--with-xml' '--enable-bcmath' '--enable-calendar' '--with-curl' '--enable-ftp' '--with-gd' '--with-jpeg-dir=/usr/local' '--with-png-dir=/usr' '--enable-magic-quotes' '--with-mysqli' '--with-mysql=/usr' '--with-openssl' '--enable-discard-path' '--without-pear' '--enable-sockets' '--enable-track-vars' '--with-ttf' '--with-freetype-dir=/usr' '--enable-gd-native-ttf' '--with-zlib' '--with-apxs2=/usr/sbin/apxs'; Everything is compiled and installed correctely. I can run php scripts normally. But i need to change display_errors = on and install eaccelerator. So i created a page with phpinfo() to find out where is php.ini. I got this Configuration File (php.ini) Path /usr/local/php/lib Loaded Configuration File (none) It seens like php.ini is not being loaded. What can i do? Thanks, Fernando.
