RSanford is absolutely correct and Casey and Spencer are on to something regarding the PHP package they speak of.
The version of Apache that shipped with PB is a DSO build.
The modules are located in:
/System/Library/Apache/Modules
and apache -l does confirm this.
If you compile...
Is a rebuild of Apache needed? I thought the idea of modules was to "Load as needed" kind of thing. Does it work like the Linux kernel, building support for loadable modules when compiling a new kernel?
