This page http://httpd.apache.org/docs/2.2/howto/cgi.html describes how to give each user his own cg-bin directory.
The following lines should be added to the Apache configuration file http.conf :
<Directory /home/*/public_html/cgi-bin> Options ExecCGI SetHandler cgi-script </Directory>
Along with this there are some more points to be kept in mind. If you .htaccess file has a section like this :
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{http_host} ^site.com [nc]
RewriteRule ^(.*)$ http://www.site.com/\ [r=301,nc]
</IfModule>
then putting the cgi configuration will give this error :
Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden
and the cgi files won't work. The solution is : Options +ExecCGI instead of Options ExecCGI
Also make sure that this line :
ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
is commented, otherwise all request to www.site.com/cgi-bin would go to /var/www/cgi-bin instead of the user's cgi-bin directory.
