[Haskell-beginners] How to change base version easily?

Hello,
I installed the latest version of ghc, which caused one of my packages does
not satisfy the constraint of the version. I just wondering if there exists
a convenient way to degrade the version of the base. I use Arch Linux,
which is not easy to install an elder version.

Thanks,
July
