Could not load library libmkl_rt

[jishnub]

I'm trying to use this package on a cluster, and came across the following error:

I remember this package working on a previous Julia version on this cluster long back.

Thanks for the issue. I can reproduce locally. This is definitely a mistake on my side (likely introduced in the big rewrite). I'll fix this soon (and will also add tests that test this...).

Will tag a new patch release with the fix in the next 30 minutes.

Thanks for the swift response!
