When considering build-time dependencies, there are many cycles that makes an 
importer almost impossible to create. There is some code that works (at least 
it used to work) when you don't need a recursive import, but it would be 
useless because most packages require thousands of packages at build time.

I haven't been working on this since quite some time, and I don't think I'm 
going to take that time soon. If anyone is interested, I still think we need to 
build a backtracking startegy in our importer infrastructure (we could have a 
constraint solver do the job, but we would need complete information about the 
npm repo. We can only look up package by package) and import a minimal path, 
taking version constraints into account. Basically, backtrack on loops.
