Fatal Error: Failed opening required

[lgonzalz]

I am using PEAR to send an email. Can anyone tell me why I get the following error?

Fatal error: Failed opening required 'Mail/Mime.php' (include_path='.:/usr/share/pear')

The code looks like this:

require_once('Mail.php');
require_once('Mail/Mime.php');

First thing to check is cases is the directory called Mail or mail on Unix systems it makes a difference.

Second thing to check is the rights on the folder and file. Do a CHMOD -R 777 Mail

If that works build down and give fewer rights.
