Pusher/Wrench on Ubuntu 12.04 with PHP - php

Question

A site I am currently grabbing a lot of data from via API recently implemented Pusher to provide real-time updates. They then link to the page http://pusher.com/docs/client_libraries for client side libraries in several languages.
So the PHP client library linked to at http://pusher.com/docs/client_libraries appears to be bad.
First, the Git repo (via browser) doesn't download everything but once you get that figured out it still doesn't work. The basic flow is connect to Psher server with App key, then subscribe to one or more channels, then listen forever to those channels for updates.
The connect appears to work. The subscribe appears to work. The top level object from the PHP library leads to a recursion error (too deep) when I use var_export on it. Here's the resulting object after I subscribe to a channel:
Wrench\Payload\HybiPayload::__set_state(array( 'frames' => array ( 0 => Wrench\Frame\HybiFrame::__set_state(array( 'masked' => false, 'mask' => NULL, 'offset_payload' => 2, 'offset_mask' => 2, 'length' => 84, 'type' => NULL, 'buffer' => 'T{"event":"pusher:connection_established","data":"{\\"socket_id\\":\\"34937.7965561\\"}"}', 'payload' => '', )), ), ))
From there it waits for an update from the channel and when an update occurs I get the following:
Wrench\Payload\HybiPayload::__set_state(array( 'frames' => array ( 0 => Wrench\Frame\HybiFrame::__set_state(array( 'masked' => false, 'mask' => NULL, 'offset_payload' => 4, 'offset_mask' => 4, 'length' => 153, 'type' => NULL, 'buffer' => '~' . "\0" . '™{"event":"pusher:error","data":{"code":null,"message":"Pusher protocol versions <= 3 have been deprecated. Support will be removed after November 2013"}}', 'payload' => '', )), ), ))
and
array ( 0 => WrenchPusher\PusherMessage::__set_state(array( 'event' => 'pusher:connection_established', 'channel' => NULL, 'data' => stdClass::__set_state(array( 'socket_id' => '34937.7965561', )), )), 1
=> WrenchPusher\PusherMessage::__set_state(array( 'event' => 'connection_established', 'channel' => NULL, 'data' => stdClass::__set_state(array( 'socket_id' => '34937.7965561', )), )), 2
=> WrenchPusher\PusherMessage::__set_state(array( 'event' => 'pusher:error', 'channel' => NULL, 'data' => stdClass::__set_state(array( 'code' => NULL, 'message' => 'Pusher protocol versions <= 3 have been deprecated. Support will be removed after November 2013', )), )),
Now the obvious issue would be the part about version 3 not being supported. The script fails on a json_decode call which is expecting a string but is getting an object.
Despite several Google searches on the matter I have not been able to find an updated library.
Has anyone worked with a more up-to-date Pusher/Wrench PHP library? Any recommendations are welcome.
Thanks
Update 04/11/14:
Pusher support was kind enough to take 2 days to confirm that the library is in fact broken. And to tell me that they won't do anything about it. So if you want Pusher client in PHP you appear to be out of luck for now.
I also know Ruby and checked into that library. It also looked old but I didn't spend a lot of time looking into the details. After wasting my time on the broken PHP library I assumed the Ruby one was probably broken as well. Pusher seems to prefer javascript.
