PHP.ini not to be found - PHP 4.06 on MacOS X

Hey there, I use PHP on MacOS X and keep running into errors while trying to get a tutorial e-commerce site up and running. Warning: Failed opening '/Library/WebServer/Documents/mymarket/admin/index.php' for inclusion (include_path='.:/usr/lib/php') in Unknown on line 0 So I figured it might have to do with the PHP.ini file but that file is nowhere to be found on my system. When I <? run phpinfo(); ?> it says that it sits in /usr/lib but all that is sitting there is: bundle1.o crt1.o dyld dylib1.o gcrt1.o java libDHCPServer.A.dylib libDHCPServer.dylib libIOKit.A.dylib libIOKit.dylib libSystem.B.dylib libSystem.dylib libalias.A.dylib libalias.dylib libc.dylib libcom_err.dylib libcrypto.0.9.dylib libcrypto.dylib libcurses.dylib libdes524.dylib libgssapi_krb5.dylib libinfo.dylib libk5crypto.dylib libkmod.a libkmodc++.a libkrb4.dylib libkrb5.dylib libkvm.dylib libm.dylib libobjc.A.dylib libobjc.dylib libpcap.A.dylib libpcap.dylib libpthread.dylib libssl.0.9.dylib libssl.dylib libtcl.dylib libtcl8.3.dylib libz.1.1.3.dylib libz.1.dylib libz.dylib php PHP is a directory with the following files: /usr/lib/php /usr/lib/php/build /usr/lib/php/build/acinclude.m4 /usr/lib/php/build/dynlib.m4 /usr/lib/php/build/dynlib.mk /usr/lib/php/build/fastgen.sh /usr/lib/php/build/library.mk /usr/lib/php/build/ltlib.mk /usr/lib/php/build/mkdep.awk /usr/lib/php/build/pear.m4 /usr/lib/php/build/program.mk /usr/lib/php/build/rules.mk /usr/lib/php/build/rules_common.mk /usr/lib/php/build/rules_pear.mk /usr/lib/php/build/shtool /usr/lib/php/extensions /usr/lib/php/extensions/no-debug-non-zts-20001222 Anyone out there able to help me? thanks, Eric
