ResourceBundle in PHP
===

While trying to use the 'country' form field of the symfony 2.x framework I came upon a problem - the ResourceBundle does not want to work.

The error message I receive is:

    PHP Unknown error:  resourcebundle_create(): resourcebundle_ctor: Cannot load libICU resource bundle

The script I used while trying to determine the cause is:

    <?php
    $dir  = "vendor/symfony/src/Symfony/Component/Locale/Resources/data/region";
    $locale = 'en_US';

    $r = resourcebundle_create( $locale, $dir, true);

The OS is Linux Ubuntu 12.04. PHP 5.3.10.

    intl

    Internationalization support => enabled
    version => 1.1.0
    ICU version => 4.8.1.1
    ICU Data version => 4.8.1

    Directive => Local Value => Master Value
    intl.default_locale => no value => no value
    intl.error_level => 30719 => 30719

Does anyone know whats wrong?
Thanks!
