Issues with Haskell GHCi

I went to use GHCi last night when I got an error message:

[tijko@tijko ~]$ ghci
Loaded package environment from /home/tijko/.ghc/x86_64-linux-9.2.8/environments/default
GHCi, version 9.2.8: https://www.haskell.org/ghc/  :? for help
<command line>: cannot satisfy -package-id data-array-byte-0.1.0.1-8Yp2jYzUcCD2MHaot7tifU
    (use -v for more information)

I'm aware that since version 8.0.2.1 the default configuration in Archlinux is to ship all Haskell packages and libraries with dynamic linking.  I've never had a problem and have used pacman to install all Haskell packages, as:

pacman -S haskell-data-array-byte

I've never had any issues up until last night when I ran into that error message.  I ended up going to $HOME/.ghc/x86_64-linux-9.2.8/environments/ and removing the line containing the "package-id" and it seemingly fixed the issue.

What would get the environment file to have the incorrect "package-id" like this?  Also, I ran ghci through stack and it worked (ie. stack ghci).  Now I know that stack used a different version of ghc but how do I coordinate them so not to have misaligned builds?

Edit: Found out what I needed to configure with Stack to align ghc versions.
