How to set CGI execable for each user ?

Our students have their own virtual space of WWW homepage in /home/userID/html/,
Their URL are http://aaa.com/~userID/
Now we need to set CGI execable for each directory of users in a subdirectory.
The URL is http://aaa.com/~userID/cgi-bin/
Therefore we add a Directory tag in httpd.conf,
--Directory "/home/*/html/cgi-bin-------
AllowOverride None
Options ExecCGI
Order allow,deny
Allow from all
--Directory-----------------------------
When we run hello.pl using browser, http://aaa.com/userID/cgi-bin/hello.pl
but the browser print the source code of hello.pl.
What should we do ?

# add this line to your httpd.conf

AddHandler cgi-script .pl .cgi

I have these line in htt[d.conf:
-Directory /home/*/html-
AllowOverride FileInfo AuthConfig Limit
Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec
-Limit GET POST OPTIONS PROPFIND-
Order allow,deny
Allow from all
-/Limit-
-LimitExcept GET POST OPTIONS PROPFIND-
Order deny,allow
Deny from all
-/LimitExcept-
-/Directory-

AddHandler cgi-script .cgi .pl
ScriptAlias /cgi-bin/ "/home/httpd/cgi-bin/"

-Directory "/home/httpd/cgi-bin"-
AllowOverride None
Options ExecCGI
Order allow,deny
Allow from all
-/Directory-

-Directory "/home/*/html/cgi"-
AllowOverride None
Options ExecCGI
Order allow,deny
Allow from all
-/Directory-
The result is:
HTTP/1.1 200 OK Date: Thu, 18 May 2000 08:14:27 GMT Server: Apache/1.3.12 (Unix) PHP/4.0RC2 mod_layout/1.6 Keep-Alive: timeout=15, max=99 Connection: Keep-Alive Transfer-Encoding: chunked Content-Type: text/html; charset=iso-8859-1
OK
You don't have permission to access /~gigi/cgi/hello.pl on this server.

It's work
/home/*/html/cgi/hello.pl ----200 OK(Error)
/home/*/html/cgi/hello.cgi ---It's work
But I don't know why
Because
/home/httpd/cgi-bin/hello.pl --- It's work
