Composer Update issue on develop branch

[abishekrsrikaanth]

I get the following error when doing composer update on the develop branch as I am using Laravel 4.1

{"error":{"type":"ErrorException","message":"Declaration of Jenssegers\\Mongodb\\Model::belongsToMany() should be compatible with Illuminate\\Database\\Eloquent\\Model::belongsToMany($related, $table = NULL, $foreignKey = NULL, $otherKey = NULL, $relation = NUL
L)","file":"C:\\apache\\htdocs\\mongo_application\\vendor\\jenssegers\\mongodb\\src\\Jenssegers\\Mongodb\\Model.php","line":315}}
