stack not working?

[José Pérez]

Hi all,
is it me or stack is not working in FreeBSD?

haskell/test% stack setup
No setup information found for ghc-8.4.3 on your platform.
This probably means a GHC bindist has not yet been added for OS key 
'freebsd64'.
Supported versions: ghc-7.8.4, ghc-7.10.1, ghc-7.10.2, ghc-7.10.3, 
ghc-8.0.1, ghc-8.0.2, ghc-8.2.1, ghc-8.2.2, ghc-8.4.1, ghc-8.4.2, 
ghc-8.6.1

pkgs installed:
ghc 8.4.3_1
stack 1.7.1_1

Is there a workaround? Thank you.

Regards,
