This has also been reported on the gentoo-haskell github issue tracker: https://github.com/gentoo-haskell/gentoo-haskell/issues/1469
Like for this comment on the GitHub issue tracker: https://github.com/gentoo-haskell/gentoo-haskell/issues/1469#issuecomment-2551719624 It was solved for me by emerging dev-haskell/cabal-install first. It's a nonsense bug fix but it the trick. On another computer, I emerged directly all latest haskell packages from ::haskell, and dev-haskell/pandoc-lua-engine-0.4.1 got installed correctly without I had to first emerge dev-haskell/cabal-install.
Created attachment 919653 [details] emerge pandoc from scratch Thanks @benoit.dufour, you saved me a lot of time! I'm encountering the same issue. I'm trying to install Pandoc from scratch on my Gentoo system. I've attached two files: "pandoc-lua-engine-0.2.1.2-build.log" (build log) and "emerge -pv pandoc.txt" (emerge output). As you suggested, manually installing dev-haskell/cabal-install resolved the problem. This package is missing from the dependencies listed in the emerge -pv pandoc.txt output and should be added.
Created attachment 919654 [details] pandoc-lua-engine failed with "cannot satisfy -package-id pandoc" <command line>: cannot satisfy -package-id pandoc-3.1.8-Iblz6E732uI1jCpqtnlIYL (use -v for more information)
In fact, nothing depends on this package, 'equery d --all-packages dev-haskell/cabal-instal' gives zero list.
> "In fact, nothing depends on this package, 'equery d --all-packages dev-haskell/cabal-instal' gives zero list." Either 'dev-haskell/pandoc-lua-engine' should depend directly on 'dev-haskell/cabal-install', or should depend on one of the dependencies of 'dev-haskell/cabal-install' So that missing dependency should be added as either a BDEPENP or DEPEND to the 'dev-haskell/pandoc-lua-engine' current ebuild. Or another kind of nonsense edge-case bugfix is required.
Another solution that works for me in this context is to run emerge dev-haskell/pandoc again and after that emerge dev-haskell/pandoc-lua-engine succeeds. I have attached the old (broken) and new (working) gpkg files from dev-haskell/pandoc in case the difference between the two might reveal the underlying problem.
Ok. Here's the issue. ghc-pkg list -v produces the following warning when run in the state where the build fails: WARNING: cache is out of date: /usr/lib/ghc-9.2.8/package.conf.d/package.cache ghc will see an old view of this package db. Use 'ghc-pkg recache' to fix. Running ghc-pkg recache fixes the issue and allows pandoc-lua-engine to build without the previously mentioned hack. The question is why ghc-pkg recache is not running or not running in time. I guessing that it might be because somehow pandoc-lua-engine starts building before ghc-package_pkg_postinst is run for dev-haskell/pandoc. Would adding dev-haskell/pandoc to BDEPEND for dev-haskell/pandoc-lua-engine avoid the issue?

Add a check in haskell-cabal-pkg_setup that checks for and fixes an invalid cache.
