Sorry, may or may not be talking about the same thing here. gr-perf-monitorx requires python-networkx, which (I think) is an untracked dependency.

For utilities like this, we have not previously made Python modules a required dependency of GNU Radio. We could, but that would put an extra burden on just building the project even if you don't use the particular app or example. Generally, we try to provide a friendly message explaining the problem. PyBOMBS probably should add these dependencies, though. At least scipy.

Also, I believe I ran into this issue recently new versions of networkx that broke out a dependency that used to not be required as a separate install, which I think is what the OP's problem is related to. See PR #768:

gr-perf-monitorx. It's just been the kind of thing that everyone that uses it already has and no one tracks it. There's a couple of minor deps for utilities like this that sneak through the cracks, but they're very hard to keep track of until you run this on a brand new image.

Who is calling pygraphviz? If we need this for GNU Radio, we probably
need to update some recipes.
