I briefly read the documentation on Karrigell. You will want to do the same. It looks like it's theoretically possible to install Karrigell in Apache cgi mode. Look at section 5.2 and 5.3 of the documentation, "5.2 Apache with mod_cgi" and "Apache on shared web hosting".
If all that looks too daunting, be brave or learn perl, php, or ruby.
