Not to worry, peschkaj! You can easily restrict mod_perl operation to just a directory, or even just certain scripts. I have a .htaccess file that I use to turn on mod_perl for just two scripts, frontend and backend, that I put in their directory:

<FilesMatch "^backend|^frontend">
    SetHandler     perl-script
    PerlHandler    Apache::Registry 
    Options        ExecCGI
</FilesMatch>

The directory where you put this has to have AllowOverride enabled, otherwise you will have to add a corresponding entry into httpd.conf. If you don't want mod_perl anywhere else, make sure you comment any other sections in httpd.conf that turn on SetHandler perl-script.
