macros/defines questions - am attempting to create parallel versions install

Greetings, I've been looking at the source of php-5.2.6 with the goal of creating a port for the FreeBSD ports system that will enable the user/sysadmin to install php5 along side an already installed php 4 version. My intended course is to install the php5 cgi sapi and use a php5 directory in place of the default php directory eg; $PREFIX == /usr/local $PREFIX/bin $PREFIX/etc/php $PREFIX/include/php $PREFIX/lib/php becomes: $PREFIX == /usr/local $PREFIX/bin $PREFIX/etc/php5 $PREFIX/include/php5 $PREFIX/lib/php5 My main points of interest is if/where there are any already pre-defined macros that will assist me in changing the already defined php directory with a directory named php5 $PREFIX/etc/php && $PREFIX/include/php && $PREFIX/lib/php to $PREFIX/etc/php5 && $PREFIX/include/php5 && $PREFIX/lib/php5 I also hope to be able to re-name the following: $PREFIX/bin/php-cgi --> $PREFIX/bin/php5-cgi $PREFIX/bin/php-config --> $PREFIX/bin/php5-config $PREFIX/bin/phpize --> $PREFIX/bin/php5ize and $PREFIX/bin/etc/php.conf --> $PREFIX/bin/php5.conf In the last case I understand that the switch --with-config-file-scan-dir=${PREFIX}/etc/php exists that permits the definition of a directory to source for module/extension options. But is the macro $PHP_CONFIG_FILE_SCAN_DIR usable for this task? Can I use/define $PHP_SYSCONFDIR, or $PHP_CONFIG_FILE_SCAN_DIR to define the default name and location of the php.ini file? Any and all help /greatly/ appreciated, and thank you for all your time and consideration. --Chris ///////////////////////////////////////////////////// Service provided by hitOmeter.NET internet messaging! .
