grapher.cgi - Apache fails with Premature end of script headers

Hello All,

I have followed the "Installing Cricket for the Complete Beginner" guide.

But I can't get past the below in the apache error log;

[Sat Apr 18 09:32:52 2009] [error] [client 192.168.2.130] Premature end of
script headers: /opt/csw/apache/htdocs/cricket/grapher.cgi

Causing;

Internal Server Error
The server encountered an internal error or misconfiguration and was unable
to complete your request.

If I run the grapher.cgi script as the web server user I can redirect to a
html file that displays correctly.
It seems though that the stderror output is what is confusing Apache - I've
tried both apache2 and apache 1.3 and both can not handle this output.

Can anyone please help.
