I am using a home computer as a web server that is running fc12. I have recently setup the ability to run .cgi scripts and am having trouble getting a scheme cgi script to work.

I can use python, perl, bash, lisp, ... but for what ever reason I cannot use scheme. This is unfortunate because my original intent was to use scheme.

I am rather new to this .cgi scripting and serverside-funtimes, so I will supply as much information as I can.

As far as I can tell, my code looks fine,

Code:
#!/usr/bin/mzscheme -rq
(require net/cgi)
(output-http-headers)
I have used every combination for flagging mzscheme that I have seen examples of online, and still no good.


When I try to load the page, I get Error 500.
