Comment (by michaellass):

 Indeed, `i->pathNext->id.objID` is of type `unsigned int`, for which
 `abs()` does not make much sense. Replacing the line by the following
 should fix the issue and keep the code functional:
 {{{
 COLA_ASSERT(abs((int)i->pathNext->id.objID - (int)i->id.objID) != 2);
 }}}

 If nobody is quicker than me, I will report this upstream and add a
 corresponding patch to the Portfile.
