PHP - Mail.php and Mail/mime.php issues
 

OK, so PHP is throwing errors and I have no idea why. Basically, opening 'Mail.php' and 'Mail/mime.php' fails. The errors even indicate they're looking in the correct path (/usr/share/pear), so what gives?

Errors:
[Sun Feb 08 16:53:31 2009] [error] [client xxx.xxx.xxx.xxx] PHP Warning: include_once(Mail.php) [<a href='function.include-once'>function.include-once</a>]: failed to open stream: No such file or directory in /var/www/html/base/includes/base_action.inc.php on line 29

I've verified I do have both 'Mail.php' and 'Mail/mime.php' (and even in the correct path mentioned in the error):

[root@someids ~]# locate ".php" | egrep -i "(mail|mime)"
...
/usr/share/pear/Mail.php
/usr/share/pear/Log/mail.php
/usr/share/pear/Mail/RFC822.php
/usr/share/pear/Mail/mail.php
/usr/share/pear/Mail/mime.php
/usr/share/pear/Mail/mimeDecode.php
/usr/share/pear/Mail/mimePart.php
/usr/share/pear/Mail/null.php
/usr/share/pear/Mail/sendmail.php
/usr/share/pear/Mail/smtp.php
...

Pear output:
[root@someids ~]# pear install Mail Mail_mime

drwxr-xr-x 2 root root 4.0K Feb 8 14:25 Mail
-rw-r--r-- 1 root root 8.8K Feb 8 14:25 Mail.php
...

I've even chowned the above file/folder to apache.apache to no avail.

Here's lines 29 and 30 of base_action.inc.php mentioned in the error logs, for reference:
include_once("Mail.php"); // r.rioux added for PEAR::Mail
include_once("Mail/mime.php"); //r.rioux added for PEAR::Mail attachments

Also for reference, this is a CentOS 5.2 and its current primary services are apache, mysql, snort and base (acid). I wanted to keep it as minimal as possible too, so when I was installing the OS, I didn't include ANY additional packages. I just install packages through yum on 'as needed' basis. Is it possible I'm missing a critical php package thats usually included by default?

Not sure if this matters, but I've verified sendmail is listening on TCP port 25 and is functioning correctly.

I feel like I've tried everything. Any help would be appreciated.

I'm thinking its a permission issue... SELinux is turned off, and the following doesn't work either:

[root@someids ~]# chmod 777 /usr/share/pear
[root@someids ~]# chmod 777 /usr/share/pear/Mail*
[root@someids ~]# service httpd restart

AHHHHH!
