The hackage store of haskell packages allows maintainers to update package metadata directly on hackage without updating the associated archive of a package. For instance, the cabal file of the integer-logarithms package version 1.0.3 [0] has been updated since 1.0.3 was published, relaxing the constraints on some dependencies[1]. This means that, if I try to build the attached integer-logarithms.scm (created from guix import hackage integer-logarithms and modified to use ghc-8.8) I get the following error:

```
Setup.hs: Encountered missing or private dependencies:
base >=4.3 && <4.13

```

In ghc 8.8 the base version is 4.13, and the updated cabal file for integer-logarithms amends the constrants to allow that version.

The solution might be to use `cabal get` to download the archive instead of downloading the .tar.gz directly, or manually amending the cabal file after downloading.
