I'm curious why you don't just compile the binary and put it in 
the CGI directory. That's what I've always done. This AFAICT (I 
don't often use Dub) is going to compile every time it runs, 
which makes the program unnecessarily slow, and if it's used 
heavily, will add quite a load to the server. If you use Adam's 
cgi.d, you can test your program at the command line, and even 
run a server on localhost to test it in your browser.
