htdig, basic cgi-bin question

Hey folks, installed htdig and got it running from the command line correctly, but not from the pretty web interface. Just going through trying to apply my limited knowledge to see where the problem is. ie needing .cgi on the end of htsearch, etc...

When hitting the search button, getting a page not found, but I believe the address is correct in pointing to the cgi program. Any basic steps here you could share with me would be greatly appreciated. Thanks!
