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:
```

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.
