As Manjaro (Arch derivative) user learning Haskell I am a little struggling 
to set up functional environment for working with Haskell. Currently, I 
have landed on using `ghcup` + `cabal` to manage everything haskell 
related. I have good experience with `rustup` + `cargo`, so I hope my 
experience with `ghcup` will be also "UP."

With that, I am landing on compiling pandoc from source, not downloading 
binary package. Compilation with ghc v. 8.10.5 works as expected, but with 
ghc 9.0.1 (latest I believe) it fails with this output:

```

characteristics that caused the previous version to fail: excludes
'template-haskell' version 2.17.0.0)
[__8] fail (backjumping, conflict set: data-accessor-template,
pandoc-crossref, template-haskell)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: pandoc, yaml, pandoc-crossref, base,
template-haskell, data-accessor-template, transformers, skylighting-core,
containers, unicode-collation
Try running with --minimize-conflict-set to improve the error message.
```

Is it known state of things, or is it some error on my side?
Thanks in advance for any guidance in this, regards
Tomas
