cgi - switch not working?!

hi... i have compiled php as a cgi binary on my linux box. i want to be able to tell the binary which ini file to use on the command line, which i thought would be the -c switch. entering: ./php -? reveals: Usage: php [-q] [-h] [-s [-v] [-i] [-f <file>] | {<file> [args...]} -q Quiet-mode. Suppress HTTP Header output. -s Display colour syntax highlighted source. -f <file> Parse <file>. Implies `-q' -v Version number -C Do not chdir to the script's directory -c <path> Look for php.ini file in this directory -a Run interactively -d foo[=bar] Define INI entry foo with value 'bar' -e Generate extended information for debugger/profiler -z <file> Load Zend extension <file>. -l Syntax check only (lint) -m Show compiled in modules -i PHP information -h This help but entering either of: ./php -c /path/to/ini/ mytest.php ./php -c /path/to/ini/php.ini mytest.php tells me that it is using the following (and incorrect) ini file: /usr/local/lib/php.ini does anybody know how to accomplish this? regards, jamie burns.
