I don't understand, did the C program work? :-)

Why is this a class method?  You should have done something like

   free: arg [
      <cCall: 'ber_free' returning: #void args: #(#self #int)>
   ]

   free [ self free: 0]

and likewise:

This should also use an instance-side method.

Now it would be a nice exercise to turn it into a more Smalltalk-like API.
