It is always dangerous to give any advice about OpenBSD's apache,
because it is not true "apache.org" apache, but a hacked-up version
that was frozen in time years ago when Theo decided he didn't like the
Apache 2 License.

But anyway, this problem is fairly standard and is addressed here:
http://httpd.apache.org/docs/1.3/howto/cgi.html#butitsstillnotworking

The error means that apache is perfectly happy to launch your CGI
script, but the CGI is failing in some way.

The first thing to try is running the CGI from the command line:
cd /path/to/cgi-bin
./test-cgi
