I'm trying to use Network.FastCGI with Apache2, but running into an 
error.  I'd like to believe that the web server is configured correctly,
 because I can successfully view the following, compiled to <web 
root&gt;/fastcgi/test.fcgi:<br>
<br>#include &lt;fcgi_stdio.h&gt;<br><br>int main(void){<br>  int count = 0;<br>  while(FCGI_Accept()&gt;=0){<br>   printf(&quot;Content-Type: text/html\r\n&quot;);<br>   printf(&quot;\r\n&quot;);<br>   printf(&quot;Hello, World: %d&quot;, count++);<br>

  }<br>  return 0;<br>}<br><br>Now I compile Fcgi.hs to &lt;web root&gt;/fastcgi/test2.fcgi:<br><br>import Control.Concurrent<br>import Network.FastCGI<br><br>action :: CGI CGIResult<br>action = do<br>        setHeader &quot;Content-type&quot; &quot;text/plain&quot;<br>

            ]<br>
<br>main = runFastCGIConcurrent&#39; forkIO 10 action<br><br><br>When I view
 localhost/fastcgi/test.fcgi, I get the hello world page, but attempting
 to view test2.fcgi shows an &#39;Internal Server Error&quot; in firefox.  The 
apache error log says:<br>
