ngx_http_perl_handler_init should stay in postconfiguration init phase. What
you should do to use this feature conditionally is to use yourcf->enable
flag (for working example check ngx_http_autoindex_module.c).

This is because you don't set new handler but you are adding new one to the
processing chain and your handler will be called for every single request
(so you must return NGX_DECLINE as soon as possible when it isn't enabled).
