Cool!

For now, it is either packages from Pkg.jl or either packages julia-*
from Guix.  A patch [1] is still pending for being able to mix both.
Aside that packages from Pkg.jl do not always work out-of-the-box,
sadly.

IIUC, you installed all the packages using Pkg.jl, right?

Because then, I get:

--8<---------------cut here---------------start------------->8---

--8<---------------cut here---------------end--------------->8---

and I do not know if Pkg.jl works correctly with the current julia
from Guix.  For instance, "guix shell julia -CN -- julia" then 'using
Pkg; Pkg.add("Plots")' reports failures.  One is reference to build
directory "/tmp/guix-build-julia-1.6.2.drv-0", see [2].

Well, I do not know where does the issue come from.  I suspect
something related to [2] above.

For now, I do not have a solution and I do not have time to work on
it.  Sorry.  I would be happy if someone fixes the issue; probably
patch#51319 helps here. :-)
