just saw the same error but I guess this is because my perl is built
multi-threaded and pyperl has some problems with that.
The main problem is that pyperl is essentially unmaintained for 5+ years now and
nobody is actively developing this. I guess several internals and assumptions
changed in the meantime which require some ammount of coding.
