Bernoulli failures on SymPy 1.12

[cbm755]

I thought I fixed this kind of thing... Maybe 1.12 is not < 1.12.dev?

My guess is this is what you get without pip install packaging... will try that in the Fedora package and then try to adjust this before the next release...

background: our implementation of Version is sloppy without packaging.
