I meant more along the lines of tracking an issue through transitive dependencies, and then having to make a change at each step before the fix is apparent in the code you were actually writing.
I once found a weird import issue in a Google App Engine demo that, IIRC, traced back through to pip, virtualenv, and eventually setuptools.
