Hello!

With channels flourishing, we found a bug that’s always been there.

When channel C depends on B, which depends on A, in general you need
both A and B to be present in the build environment of C (the derivation
that compiles C when you run ‘pull’ or ‘time-machine’) because
potentially B is going to load modules from A.

However, currently only B is present in C’s environment.

To illustrate that, the script below creates three such channels.
Right now it fails like this:

--8<---------------cut here---------------start------------->8---
