WSOD

After partially following the setup instructions, visiting ./admin/reports/status/memcache results in a WSOD. Drupal's log reports:

Warning: require_once(/var/www/drupal/sites/all/libraries/memcache/etc/config.php): failed to open stream: No such file or directory in require_once() (line 35 of /var/www/drupal/sites/all/libraries/memcache/memcache.php.inc).

Line 35 actually references to config.php file that does not exist:

if (true === file_exists($localConfig)) { 
    require_once $localConfig;
} else {
    require_once __DIR__ . '/etc/config.php';
}

The part I skipped during the setup of this module is "…you will also want to remove the $MEMCACHE_SERVERS variable in your memcache.php.inc file." It's not clear to me what occurence of $MEMCACHE_SERVERS should be removed (there are multiple).

Also, the URL referenced in README.txt isn't valid anymore:

# wget http://svn.php.net/viewvc/pecl/memcache/trunk/memcache.php?view=co

I downloaded the file from https://github.com/lagged/memcache.php/blob/master/memcache.php, which might be different.

Also it might be relevent which file permissions are required for the libraries' folder and the renamed file.

Thanks!
