Yes, maybe that explains why I can not find the place where I need to add -ldl to make it build on amd64. > >Are you sure you have binutils-gold installed? > > Yes.

I assume the latter patch works only for amd64 and will fail on all other arches, does it need an arch specific extension for every other CPU? So perhaps the first solution is better, is there a reason why -ldl is not included in the unix rule?
