Hey Max,

We've had many user reports over the last year re the entire situation, 
including a number recently about pypy in particular.

Feel free to reach out to python@ and we'll sort something out together.

We're on IRC (#freebsd-python @ libera) or you can email me off list and 
we can work out a good place.
