Not exactly the same problem. In MongoDB's case, the problem is that both
mongodb and polarssl export the same function. This situtation is known as
clash. It would not be a problem if they worked the same way, but unfortunately
they do not, and for the moment, neither mongodb or polarssl author has
renamed their function.
