I should/will revise that in the next version. Probably with a stderr message 
and an exit(1) analog.

It should not be necessary; the next version should check four things in turn.
- the granparent directory of ntpc for the clients under regular bin_test
- the great-grandparent folder for pylib tests
- LIBDIR for people like us who have compiled it
- the system library search path for people getting it from their distro
