You get an error message like this:
Invalid command 'PerlModule', perhaps mis-spelled or defined by a
module not included in the server configuration.
You do not have mod_perl correctly installed for Apache. The PerlHandler and PerlModule directives in Apache *.conf files are extensions enabled by mod_perl and will not work if mod_perl is not correctly installed.
Common user errors are not doing a 'make install' for mod_perl, which installs the perl side of mod_perl, and not starting the right httpd after building it. The latter often occurs when you have an old apache server without mod_perl, and you have built a new one without copying over to its proper location.

To get mod_perl, go to http://perl.apache.org
