Re: Issue building with ghc-9.8.2 and packages unix, directory, filepath and os-string

The problem is that `--allow-newer` tells cabal to ignore dependencies'
upper bounds completely. If those bounds turn out to be necessary in some
cases, the solver will produce a bad build plan. Using finer-grained
(per-dependency) `--allow-newer` can avoid this by only permitting the
solver to ignore specific constraints.
