suexec / php

I've tried lots of ways to get a cgi install of php working with apache..and cant seem to get it working ... here is my last attempt I compile php with ./configure --prefix=/usr/local/php --enable-track-vars --enable-force-cgi-redirect --with-gd=../gd1.4 --with-mysql=/usr/local/mysql and I link that to /usr/bin/php .. i just rename my script to .cgi and chmod 755 it .. put #!/usr/bin/php on top.. i think it should work under suexec .. but it doesnt I tried other ways where I added AddType and Action entries into apache with a new file type .pgi .. but I couldnt get it working I just get lots of Error 500's.. before, I dont know how, but I had it partially working, the php binary ran and ouptted "no input files specified" or something like that anyway, i'm probably doing something wrong so can somebody just tell me what to add to apache and what ./configure options to compile php with to get it working with apache p.s. I want .pgi under cgi install to work with suexec and .php .php3 are already working fine under module install .... thanks in advance
