Solver requires that cabal be on your PATH
Try running 'stack install cabal-install'

Stack version

$ stack --version                                                             
1.9.3 x86_64 hpack-0.31.2

Method of installation

Installed stack from nixpkgs

Comments

cabal is installed:

$ cabal --version                                                                                   
cabal-install version 2.4.1.0
compiled using version 2.4.1.0 of the Cabal library

As it was said in #4410 solver was not check/updated for versions of cabal-install newer than 1.24 so it was removed from master. I think we should close this one as WONTFIX.
Regarding your listing of cabal --version @SomeDer - locally installed cabal-install won't get used by default as Nix mode is pure by default (see the --pure flag in the log you posted). You could try working around that either by using impure nix mode (e.g. with --no-nix-pure) or by adding cabal-install into nix packages or your project. But as I've said - solver was tested to work only with cabal-install-1.24 so I'm not sure if it's worth trying those out.
