Version mismatch between ghc and ghc-pkg when specifying the ghc version in cabal.project

[tchoutri]

• HLS version: haskell-language-server version: 2.11.0.0 (GHC: 9.10.2) (PATH: /home/tchoutri/.ghcup/hls/2.11.0.0/lib/haskell-language-server-2.11.0.0/bin/haskell-language-server-wrapper)
• Cabal version: cabal-install version 3.16.0.0

While using HLS in a project that specifies the GHC binary in cabal.project, I get this error:

  Error: [Cabal-4000]
  Version mismatch between ghc and ghc-pkg:
  /home/tchoutri/.cache/hie-bios/wrapper-b54f81dea4c0e6d1626911c526bc4e36 is version 9.10.2
  /home/tchoutri/.ghcup/bin/ghc-pkg is version 9.6.7

And yes indeed, 9.6.7 is the default version set on my system, but I specify 9.10.2 in cabal.project.

I will try to help HLS with this patch:

diff --git a/cabal.project b/cabal.project

Unfortunately that does not work, there's still the same error:

  Error: [Cabal-4000]
  Version mismatch between ghc and ghc-pkg:
  /home/tchoutri/.cache/hie-bios/wrapper-b54f81dea4c0e6d1626911c526bc4e36 is version 9.10.2

@fendor does hie-bios need to be taught how to handle with-hc-pkg?

[fendor]

Perhaps you are running into #3730?

Is this HLS built from source or ghcup bindist?

Some logs would be helpful in this case :)

[tchoutri]

@fendor this is taken from GHCup.

Then the issue #3730 is still relevant for you.
I am not sure why the issue could occur for ghc-pkg. We do pass --with-hc-pkg... So, logs are still welcome.
