Cannot require Zend/Config/Ini when Zend is in the include path?

Question

When I try this:

require_once 'Zend/Config/Ini.php';

I am getting this error in my Zend Framework application:

Warning: require_once(Zend/Config/Ini.php) [function.require-once]: failed to open stream: No such file or directory in /path/to/functions.php on line 408

When I print out my include path, it is:

string(101) "/path/to/www/app/modules/:/path/to/www/lib/:.:/usr/local/share/pear"

I have ZF library in the /path/to/www/lib/ folder, so wtf?

Answer 1

This solved the problem:

chmod -R 755 /path/to/www/lib

Blimey!
