Afaik you do not need the symlink. It may even harm. I still regard homebrew
Nim as a bad way to install Nim until it stabilizes.
Nim uses the std lib by using the path the Nim binary is located. Thats also
why `nim-vm` <https://github.com/ekarlso/nim-vm>`_ easily can install and
maintain multiple versions of Nim.
Installing Nimble works just as described in the docs in
https://github.com/nim-lang/nimble in the Unix section.
