I'm hoping to get a little assistance with configuring PEAR to work properly. I have a PHP file that's calling PEAR's mail and mail-mime files, and I believe I am missing some steps because I keep getting the very common

Warning: include_once(Mail.php): failed to open stream: No such file or directory
Warning: include_once(Mail_Mime/mime.php): failed to open stream: No such file or directory

It is installed -

Installed packages, channel pear.php.net:
=========================================
Package          Version State
Archive_Tar      1.3.7   stable
Console_Getopt   1.2.3   stable
Mail             1.2.0   stable
Mail_Mime        1.8.3   stable
PEAR             1.9.4   stable
Structures_Graph 1.0.4   stable
XML_RPC          1.5.4   stable
XML_Util         1.2.1   stable

And according to this TUT, I need to configure it appropriately in each vhost. I have already gone through and adjusted the php.ini file, but when the TUT speaks of the

php_admin_value open_basedir "/var/www/vhosts/example.com/httpdocs:/tmp:/usr/share/pear:/local/PEAR"

in my /var/www/vhosts/example.com/conf/httpd.include file I kind of get lost. There are several httpd.include files in that directory, all preceded with very long numerical strings.

All I want to do is have an email attachment in my form....

Any insight or similar experiences shared would be greatly appreciated.
