I recently ran into an issue where cabal
had resolved the sdl2
package to a really old version since I hadn't specified the bounds for the sdl2
dependency. I was trying to import a module that exists only in newer versions of the package and then I was greeted with the following error:
app/Main.hs:5:1: error: [GHC-87110]
Could not load module ‘SDL’.
It is a member of the hidden package ‘sdl2-2.5.5.0’.
Perhaps you need to add ‘sdl2’ to the build-depends in your .cabal file.
Use -v to see a list of the files searched for.

It took me a while to figure out that the version of sdl2
that cabal was using was actually 1.2.0
and adding explicit bounds to sdl2
fixed the issue.
I think this error message could be improved to something like this:
app/Main.hs:5:1: error: [GHC-87110]
Could not load module ‘SDL’.
It is a member of the package `sdl2-2.5.5.0`, but you're currently using `sdl2-1.2.0`.
Perhaps you need to add explicit bounds to the `sdl2` dependency in your .cabal file.
Use -v to see a list of the files searched for.
