(I was thinking of cross-module dependencies, quite possibly involving
multiple authors)

Like documentation?  I suppose this is a programmers' mindset thing.

Examples to cut and paste from, would be my vote.  Which is why I like
to stress installing libraries as source.

Of individual components, but not of the whole repository as such.

Anyway, I'm not sure dependencies will be so crucial for Haskell
source, most incompatibilities should be caught at compile time by
type checking, a luxury Linux distributions don't have to the same

Some dependencies on specific behaviour is caused by the need to work
around bugs, this could be alleviated by having source and an obvious
path for updates -- i.e. instead of working around a bug, I can fix
it, and send the fix upstream.

If I haven't seen further, it is by standing in the footprints of giants
