collective.twitter.accounts auth problem

I'm unable to get twitter accounts to authenticate.

It has been working fine on my other sites (different server), but testing it today had the same problem.

I get errors when requesting the token, using the PloneTweet "app" on the control panel (builtin).
I also tried setting up my own custom "app" at dev.twitter.com, got all the various secret info, tokens and so forth, but still no joy.

Plone 4.3.2 UI

Traceback (innermost last):
  Module ZPublisher.Publish, line 138, in publish
  Module ZPublisher.mapply, line 77, in mapply
  Module ZPublisher.Publish, line 48, in call_object
  Module collective.twitter.accounts.browser.token, line 94, in __call__
AttributeError: 'module' object has no attribute 'SignatureMethod_HMAC_SHA1'

Is anyone else using this package? 
I'm wondering if twitter has changed something in the API which has broken this package?

Can other users, or the developer confirm that it's working for them?
Again, I've used it successfully on another site, but noticed this evening that tweets have stopped showing up there as of a few days ago.

Thanks!
