thanks for letting me know, I will start by having a look at the patches
doing version updates.

Concerning sagemath itself, below is my very old version of an attempt at
packaging the library. Some things look reassuringly similar, my handling
of the number of cores is less nice, but I do delete the bundled packages.

Maybe you could copy useful parts into your recipe?

As for tests, indeed we should drop them for the time being until we have
a working sage package.

Thanks for these efforts!

Andreas
