lbraun pushed a commit to branch master
in repository guix.

commit 39c97cf3d03e2a5f7929654ecf92e92ab03bb953
Author: Lars-Dominik Braun <lars@6xq.net>
AuthorDate: Fri Jan 6 12:46:26 2023 +0100

    build: haskell-build-system: Process all transitive dependencies.
    
    A bug caused install-transitive-deps to stop looping if a dependency
    file already existed in the target directory. For Haskell packages
    with multiple libraries (like attoparsec) this resulted in missing
    dependencies and error messages like this:
    
        The following packages are broken because other packages they depend
        on are missing. These broken packages must be rebuilt before they
        can be used.
        installed package attoparsec-0.14.4 is broken due to missing package
        scientific-0.3.7.0-9XG3zUjXOw970JFcruv0cZ
    
    See <https://issues.guix.gnu.org/54729#11>.
    
    * guix/build/haskell-build-system.scm (register): Unconditionally loop
    over all tails.
