The apache error log location varies. If you have a fully blown server it is probably at:

/var/log/httpd/error_log
# or perhaps
/usr/local/apache/var/log/httpd/error_log

# to see the error do
tail -n10 /var/log/httpd/error_log
# this gives you the last 10 lines

If you are in a virtual server environment the logs may be there (you may or may not have access) or the sysadmin may have given you personal logs somewhere.

Try reading the CGI Help Guide and follow the suggestions ie add the BEGIN block with the header and the 'fatalsToBrowser' bit. This should get the error into your browser window as well as the logs.
