apache trying to execute cgi man pages

I'm getting some errors that are making me nuts when I access the man pages for the cgi programs

The apache log shows this:

Options ExecCGI is off in this directory: /home/xymon/server/www/help/manpages/man1/ackinfo.cgi.1.html, referer: http://server.org/xymon/help/manpages/man1/

And of course, when I add ExecCGI I get:

Premature end of script headers: ackinfo.cgi.1.html

The server is scientific linux 6

Suggestions?
