ghc: depends on llvm-3.5, which is not supported on Sierra

[claus.atzenbeck@…]

I've updated to macOS Sierra and MacPorts 2.3.4. When doing a "sudo port upgrade outdated" (after "sudo port selfupdate"), I get the message that llvm-3.5 is not supported on macOS Sierra or newer (see below). How can this issue be resolved?

In the future, please fill in the Port field and Cc the port maintainers (port info --maintainers llvm-3.5), if any.

This is intentional; we will not be supporting old versions of LLVM on Sierra.

If you use LLVM directly, you should switch to the latest version (llvm-3.9).

If not, you should find the port(s) that depend on it and reinstall them with the variant corresponding to the latest LLVM. What does this output?

$ port dependents llvm-3.5 clang-3.5

Dependencies: llvm-3.5 <- ghc <- pandoc

I have removed all of those dependencies, which solved the problem. However, pandoc still depends on llvm-3.5. I guess that this will be changed in the future.

Thanks for the pointer.

So this is a duplicate of #52221, which was folded into #48899.

Yeah, the following ports seem to have direct dependencies on fixed versions of llvm and should probably be looked at:

faust2-devel ghc julia pure py-llvmlite py-llvmpy

See #52424.
