#68303: shellcheck will not build in the default variant with ghc 9.6 with cabal
-----------------------------+------------------------
 Reporter:  breiter          |      Owner:  (none)
     Type:  defect           |     Status:  new
 Priority:  Normal           |  Milestone:
Component:  ports            |    Version:  2.8.1
 Keywords:  cabal stack ghc  |       Port:  shellcheck
-----------------------------+------------------------
 After a bit of a struggle to get GHC to install
 (https://trac.macports.org/ticket/68302) I ran into another problem where
 shellcheck build fails because cabal cannot build with cabal, which is the
 default variant.

 After searching the rest of the dependency tree exhaustively, these were
 the
 goals I've had most trouble fulfilling: aeson, ShellCheck, text, base,
 semigroupoids, semialign, semialign:semigroupoids, regex-tdfa,
 transformers
 Try running with --minimize-conflict-set to improve the error message.

 The problem is that the ghc version that is bundled with macports is newer
 than the 0.90 tag of shellcheck was designed to build with.

 This patch from main will fix the constraints for cabal to ghc 9.6.1:

 https://github.com/koalaman/shellcheck/commit/b3932dfa10804434fb8c15dc32e428c5a1c3bfa4

 Otherwise maybe the +stack variant should be default.
