Hello,

python-llvmlite fails to build because it tries to download a patch that
has the wrong checksum.

Starting download of /gnu/store/hb3kk3d4nngxglfdflf99incbhmbw14h-D47188-svml-VF.patch
From https://raw.githubusercontent.com/numba/llvmlite/v0.30.0/conda-recipes/D47188-svml-VF.patch...

This is likely a regression from
6608727262f45d351c55cd1ae40414db7768a374 and would go unnoticed if you
already had the previous patch in your store with the expected checksum.

I tried to simply update the patch, but the updated patch fails to apply
on LLVM 7, and the *other* patch fails to apply if I change to LLVM 8.

There is a new version of python-llvmlite out too, but no changes to the
patches.

Not sure what to do from here, help wanted!
