Ok, all the additional failures seem to be related to cabal-helper-wrapper exiting with exit code=1. Does the executable actually exist at the path referenced in the output? Could you try running it by hand and seeing if it returns something sane?

For example, in a directory with a cabal project, after running cabal configure, the following should return the package name and version:

$ path/to/cabal-helper-wrapper . dist package-id
[Just (ChResponseVersion "cabal-helper" (Version {versionBranch = [0,8,0,2], versionTags = []}))]

The "." refers to the cabal project directory and the "dist" is the path to the dist-dir. You can give absolute paths there instead of cding into the project directory first if you like.

hm, strange. I'm using Stack to build it and it cannot be found:

D:\Projects\Hackage\ghc-mod>stack build cabal-helper --copy-compiler-tool --stack-yaml stack82.yaml
Warning (added by new or init): Some packages were found to be incompatible with the resolver and have been left commented out in the packages section.
You can omit this message by removing it from stack.yaml
