This will work by itself (assuming mod_perl statically linked), or you can just tack on parts to your existing config.
/home/lj is only an example directory. You'll want to use the same directory used in Section 1: $LJHOME Environment Variable.
If you'd like, you can put those last three lines in a VirtualHost block.
