I have problem with including mdb2 package to the system.
i have file structure:


i have script in webservice folder and it is using mdb2. if mdb2 files and its folders are in webservice directory, it is no problem with script.
If i move the mdb2 files under the pear folder and will change in incldue dir to ../lib/pear/mdb2.php then will get the problem:

Warning: require_once(MDB2.php) [function.require-once]: failed to open stream: No such file or directory in /some/dirs/lib/pear/MDB2/LOB.php on line 53

In server I can not change environment values.
but i would like to keep mdb2.php file in the lib pear folder.
Also some other packages are in the pear folder and they are working fine without any problem.

any kind of help will be useful,
