hs-yaml @0.8.10.1_1: Configure fails with missing or private dependencies

[p-bro]

When trying to install hs-yaml using sudo port -d install hs-yaml, the process fails in the configure phase with the following error message (full log attached):

(Note that this happened after a failed rev-upgrade necessary due to hs-yaml opportunistically linking to libffi.)

Build log hs-yaml

[ryandesign (Ryan Carsten Schmidt)]

The intention is to delete this port. See ​https://github.com/macports/macports-ports/pull/8636

[neverpanic (Clemens Lang)]

In e5c6a53381ccb92fa84a7ee6f422dd6afeacaec7/macports-ports (master):

haskell-platform, hs-*: Delete

It is too complicated to keep up with the development of
haskell-platform in its current state, and while there is technically
nothing wrong with the approach, it has turned out that nobody has the
time to maintain copies of the hundreds of libraries that are required
to provide the full haskell platform as defined at [1].

Fortunately, there is a more modern alternative available in the form of
stack, which works similar to virtualenvs for python. We are now using
stack (in the form of the haskell_stack PortGroup) for all Haskell tools
we are packaging in MacPorts (e.g. darcs, git-annex, pandoc or
shellcheck). It is also the best alternative for our users.

I am not marking haskell-platform or any of the hs-* ports as obsoleted
using the obsolete PortGroup, because these ports have not built
successfully for a while now, and the users that still have successfully
compiled copies of these tools and libraries would likely rather keep
them around than having them replaced by a file telling them that the
ports are obsolete.

This currently breaks the following ports:

• hedgewars
• hsshellscript
• distract
• buddha
