sdist fails with non-installed custom-depends:

[phadej]

$ cabal sdist
[1 of 1] Compiling Main             ( dist/setup/setup.hs, dist/setup/Main.o )
dist/setup/setup.hs:1:1: error:
    Failed to load interface for ‘Distribution.Extra.Doctest’
    Use -v to see a list of the files searched for.

Do we need cabal new-sdist?

[phadej]

Or is there some workaround (the dependency is in store), or how to say to sdist "Don't configure" / "Pretend build-type: Simple".

Probably yes.

or how to say to sdist "Don't configure" / "Pretend build-type: Simple".

I don't think there is a way to do this now, but it should be possible to add by tinkering with D.S.SetupWrapper.

Workaround should be to set builddir to new-build's created dist directory.

It should be noted that this issue prevents the gl package from using new-build entirely.
