Re: [pkg-haskell-tools] 01/01: Fixed bug that caused builds to fail under certain conditions outlined below. Let's consider three haskell source packages: <A>, <B> and <C>. <A> build-depends on a library package built by <B>, called <B.a>. <B.a> (runtime-)depends on an executable package built by C, called <C.b>. Neither A nor B build-depend on packages built by C. When <A> is built, it is possible that <C> is not built yet, thus <B.a> fails to install, failing the build of <A>.

quite right that this is a shortcoming of the system. I tried to make
it take binary dependencies into account, but then I noticed that I
would have to handle Provided/Depends, and reverted. I did not think of
this particular problem with non-library dependencies, so the variant
that only works with non-libraries is still useful, thanks!

I take it that this was the cause for Alexandre’s hspec problem?

Greetings,
Joachim
