I'm trying to download the HERMIT tool using the command cabal install hermit.
I dowloaded Haskell using GHCup. If I try to install with GHC 9.2.5 (recommended version by GHCup), I get errors like the following:
src\Text\PrettyPrint\MarkedHughesPJ.hs:487:43: error:
Ambiguous occurrence `<>'
It could refer to
either `Prelude.<>',
imported from `Prelude' at src\Text\PrettyPrint\MarkedHughesPJ.hs:33:8-38
(and originally defined in `GHC.Base')
or `Text.PrettyPrint.MarkedHughesPJ.<>',
defined at src\Text\PrettyPrint\MarkedHughesPJ.hs:629:3

cabal-3.6.2.0.exe: Failed to build marked-pretty-1.1.2.1 (which is required by
exe:hermit from hermit-0.7.1.0). See the build log above for details.
Given that the tool is pretty old, my suspicion is that it should work with an older GHC version. GHCup list gives me versions from 7.10.3 till 9.4.4.
If I run with GHC 7.10.3, I get a different kind of error:
Failed to build kure-2.18.6.

It is a member of the hidden package `fail-4.9.0.0@JWbBevols3d7TkSXAGkvyg'.
Perhaps you need to add `fail' to the build-depends in your .cabal file.
Use -v to see a list of the files searched for.

Very weird, since GHC 7.10.3 is recommended?
So, having no other options, I continued exploring versions. For GHC 8.0.2, I got yet another error:

I even tried installing on a virtual machine on the latest Ubuntu (my host PC is Windows 11), but I was stuck with the same kind of errors.
What should i try next? How to set a GHC in GHCup which is not listed anymore as availible? (an older GHC version may be the answer). Since I get this text back:

PS: I would like to stick to GHCup because it makes handling dependencies easy, I also tried downloading binary packages and that way I got stuck in another error...
