auto_prepend using .htaccess on shared host

I've just installed a web stats logging utility (PHP/MySQL) and now find myself in the situation where I need to prepend the logging script to all files served from my document root on my shared server space. Whilst the setup I have allows me to include the file ok from PHP served files, I can't however do this easily for the perl cgi scripts I have.

I've read a few posts about this topic on this forum, but none of the threads made mention of auto prepending a php file to all files in a dir and it's subdirs using only a .htaccess file. Is it possible?

thanx in advance
