There used to be package ghc-bootstrap, but it was not used anymore (and even that couldn’t work without manual intervention). I asked fabled about it and he explained me that ghc-bootstrap was only temporary for initial bootstrap, now ghc depends on itself and it must be probably manually installed on the builder when bootstrapping.
I did some time ago, when we had ghc-bootstrap package.
If this is the case, then it, too, is no longer policy compliant.

The same situation of being policy non-compliant?

Manual intervention on the builders does not seem like a good idea to
me, which is probably why it's not compliant with policy.
I suspect the ghc-bootstrap package was dropped because of the
depsolver bug I solved back in April.
The bootstrap package would have a provides entry for the compiler
with a version of 0.
This would allow the real compiler to always "win" the preference.

You could do that, or what I was inferring was that the binary itself
was still available on distfiles.alpinelinux.org.
All the builders copy their sources to that server.

Instead, lets solve these problems correctly, please.
Indeed, the only thing we have learned today is that Haskell is also broken.
