There are certain bootstrap cases where circular dependencies are largely

Take for instance the case when you're building with a compiler in pkgsrc.
You either have to accept that some of your packages will not be built
with the compiler of your choice (which is what we currently do), or you
have to go through the song and dance of compiling enough to build your
compiler, and then recompiling it all so that it's built with the correct

It wouldn't be impossible to implement some sort of generic framework to
bootstrap circular dependencies, but nobody has yet wanted it strongly
enough to do it.
