You're missing Module.symvers from zaptel's compiled source. As a
workaround, you can build the package and copy it from the source by hand .

I'd say that bulding external modules based on zaptel packages it's not
exactly supported (i.e. you're on your own) but Tzafrir may disagree
and/or know more.
