How do you force Haskell's cabal-install program to ignore system libraries?

I'm trying to install the accelerate library from hackage, but it keeps giving me an error saying that my version of base package (4.15.1.0) is too new. Is there a way to force it to ignore the base package that's installed as a system-wide package, and instead download the correct version of the base package?

I'm using Manjaro Linux, ghc version 9.0.2, and cabal version 3.4.0.0. I can't seem to find any documentation on how to force it to ignore a system package. I've tried searching on https://cabal.readthedocs.io/en/3.6/ , but it doesn't seem to mention it anywhere.

The base package is always hard-fixed to the compiler version. The only way to switch base is to switch to a different GHC. That's easier with Stack than it is with Cabal-install – just select a snapshot that has a suitable base version (lts-18.24 would do), and Stack will automatically install the corresponding compiler.

But it could well be that you can actually use base-4.15, and just accelerate has conservative dependency bounds. Try installing it with --allow-newer=base. If that works, give the maintainers a PR that the version bounds can be relaxed.
