Looks like error has been addressed in Github but still pipy installer/wheels in Pipy needs to be updated

@gogasca I fixed it by installing these libs
!apt-get install libgmp-dev libmpfr-dev libmpc-dev

It is both already addressed in the current master, plus there is an explaination of the solution in both the getting started and the faq pages
