Description of problem:
After installing a package to a zend-6.1 app, the app does not load the installed package by looking up $OPENSHIFT_DEPENDENCIES_DIR by default, causing the packages unusable. Moreover, a user needs to explicitly give the complete absolute path to load the package. On the other hand, there is no such problem for zend-5.6 apps.

Version-Release number of selected component (if applicable):
devenv_4084

How reproducible:
always

Steps to Reproduce:
1. create a zend-6.1 app

2. install a package to this app, for example, Validate-0.8.5 (the latest stable version)
echo "channel://pear.php.net/Validate-0.8.5" > deplist.txt

3. create a test page(dependency.php) under $APP_REPO/php to use the installed pakcage. In this step, we load the package with the relative path of the package.

<------dependency.php---->
<?php

// Here we use the relative path of the package
include "Validate.php";  

if (Validate::number(8.0004, array('decimal' => '.', 'dec_prec' => 4))) {
    echo 'version 1';
} else {
    echo "Invalid number";
}
?>

<------------------------>

4. push the change

5. visit the $APP_DNS/dependency.php page

6. load the package with the absolute path of the installed package:

include $_ENV[OPENSHIFT_DEPENDENCIES_DIR]."/pear/pear/php/Validate.php";

7. push the change and visit the dependency.php page again

Actual results:
In Step 5, it returns error 500 when visiting the test page. However, after loading the installed package with a absolute path, the page is accessible.

Expected results:
Zend-6.1 apps should look up installed packages from $OPENSHIFT_DEPENDENCIES_DIR by default.
