thanks for the answer, but this generete an error

Symfony \ Component \ Debug \ Exception \ FatalErrorException (E_ERROR) Call to a member function getAuthorizationUri() on a non-object

In my project this works ok.

You run composer update in your root aplication, and add referente into alias e and services providers in app.php

Now work with this code

public function loginGithub(){  
            $code = Input::get( 'code' );
            $gh = OAuth::consumer( 'GitHub', 'http://programacion.tips/login/github', null);
            if ( !empty( $code ) ) {
                $token = $gh->requestAccessToken($code);
                $result = json_decode( $gh->request( '/user' ), true );
                $uid = $result['id'];
                $profile = Profile::whereUid($uid)->first();
                if (empty($profile)) {
                   $user = new User;
                   $user->name = $result['name'];
                   $user->email = $result['email'];
                   $imagenPerfil = $result['avatar_url'];
                   $user->photo = $imagenPerfil;
                   $user->save();
                   $profile = new Profile();
                   $profile->uid = $uid;
                   $profile->username = strtolower($result['login']);
                   $profile = $user->profiles()->save($profile);
                }
                $profile->save();
                $user = $profile->user;

                Auth::login($user);
                Session::put('u_id', Auth::user()->id);
                return Redirect::to('/')->with('message', 'Logeado con Github');
            }
            else {         
                $url = $gh->getAuthorizationUri();
                return Redirect::to( (string) $url );
            }
    }
