nix-review pr succeeds on both macOS and Debian.

scikits-odes 2.5.0 was released, which should work with sundials 4.1.

There were plans on removing pkgs/development/libraries/sundials/3.x.nix, meaning this would bump sundials for scikits-odes, too.
@idontgetoutmuch did you check if scikits-odes builds with sundials 5.x, too?

Anyways, this shouldn't block this PR.

@GrahamcOfBorg build sundials

Yes it builds but they seem to have released

https://computing.llnl.gov/projects/sundials/download/sundials-5.0.0-dev.2.tar.gz
https://computing.llnl.gov/projects/sundials/download/sundials-5.0.0-dev.1.tar.gz
https://computing.llnl.gov/projects/sundials/download/sundials-5.0.0-dev.0.tar.gz

I validated dev.2. I can submit a PR to nixpkgs for sundials but should we wait until they release a final version? TBH it's not much work so I'll submit a PR which can be rejected if people want to wait.

Oh my bad - let me check the non-dev version.

That works but you already knew that ;-)

It does not build with sundials 5.0 - the maintainer(s) of scikits-odes will need to do something as the directory structure / naming conventions have changed. See bmcage/odes#98 (comment).
