Pre-compilation fail for MXNet.jl

[ghost]

Every time I try to import MXNet in Julia, I get the following error. Is it a problem of my configuration or something more general? I just can't figure it out from the error message.
I use Linux, in particular I'm on Manjaro-i3. The system is up-to-date but I also tried with older images.

I also get this error on Ubuntu 19.10.

It is a weird error, because it should be fixed by #16610
But for some reason an older version of build.jl is downloaded when installing via Julia's package manager.

The package version in Julia's package registry is still at 1.5.0, that is probably the issue.

Can anyone bump the Julia package in the registry to 1.6.0?
