php script doesn't accept sockets

What steps will reproduce the problem?
------------------------------------------------------
1. attempt to use the ss_get_mysql_stats.php script with a socket.

What is the expected output?
------------------------------------------------------
i expect the script to preform just like it does with tcp/ip based 
connections.

What do you see instead?
------------------------------------------------------
Cannot connect to mysql server and app crash

What version of the product are you using? On what operating system?
------------------------------------------------------
1.1.1 on RHEL5.2 with MySQL 5.1.26

Please provide any additional information below.
-----------------------------------------------------------
in our environment, for security reasons, we run with --skip-networking. 
Only socket connections are allowed.

per php.net/mysql_connect, you can pass the location of a socket as the 
hostname via this pattern:  ":/path/socket". This worked OK but the 
$cache_file is constructed from the hostname, so I made a patch to strip 
out the ":" and any "/" in the hostname.

function ss_get_mysql_stats( $options ) {
<snip>
   $cache_file_name = str_replace(array(":", "/"), array("", "_"), 
$options[host]);
   $cache_file = "$cache_dir/$cache_file_name-mysql_cacti_stats.txt";
<snip>
}
