Did anybody compile the mod_dtrace module for Apache?

[overmind]

I am looking for a tutorial regarding this topic.

I've found this but don't know if it works ok on FreeBSD: http://prefetch.net/projects/apache_modtrace/index.html

I haven't played with DTrace yet but according to the handbook you do need to specifically enable it for it to work.

So I'm guessing you need to enable DTrace on the system first before trying to build that apache module.

26.3 Enabling DTrace Support

I did enable it. Also I am looking for a DTrace PHP module (there's one for Solaris).

Update: A little bit offtopic but still related to Apache. I've managed to use DTrace with PHP. As of php5-5.4.3 (which is in Ports right now) there is support for DTrace.

After you've compiled and installed PHP and restart Apache you will see dtrace providers for php:
