problem with login_with_facebook.php

Hi, I have a problem with login_with_facebook.php. After authorization on facebook server I get a error message:
[error] => it was not possible to open the OAuth access token URL: 111 could not connect to the host "graph.facebook.com"

[debug_output] => OAuth client: Checking if OAuth access token was already retrieved from https://graph.facebook.com/oauth/access_token
OAuth client: Checking the authentication state in URI /wp-votes.php?action=fb&code=AQDHTKPDLTm6W7nNQoweicUiMRxJamNNa799jXwYfZF3qGjTdseVmRgPpzGtKjinZMIZj_pTWskPEvjnn4SQC0bKHJfVo3O35B-1i-BMq9Q29RgP7xnzAWvg8W_Q7YovISBIdI0ePVmhp0Sxzb__4OMDFOo1YtZUrFeMxyLAoMJeVNpQNGqyTyQ2wIBoXA0deEqACccUD6Au2jFQEM8U0bnV&state=1364638822-1e9b7f

How I can solve it?

This is a connectivity problem. It is not an issue with the class. It may happen once in a while. You need to anticipate in your application that it may not be possible to access Facebook API temporarily.

I just downloaded this package. The very first line requires a file that is not in the package, "require('http.php');" Where is this file, or do I not understand what this is supposed to mean?

Found it! It is another package, dependencies, and can be found here:
