pydotplus is a fork of pydot that has not been released since 2014, and is imported when pymake is imported. pydot provides the same interface, is maintained, and is what the networkx dot interface is written against.
pydot is only needed to plot dependency graphs, which also needs the graphviz binaries that pip cannot install. The import is guarded so pymake imports without it, and plotting reports what to install.

pydotplus is a fork of pydot that has not been released since 2014, and was imported when pymake was imported. pydot provides the same interface, is maintained, and is what the networkx dot interface is written against.
pydot is now an optional dependency, installed with
pip install mfpymake[plot]. Plotting a dependency graph also needs the graphviz binaries, which pip cannot install, so an install no longer carries a dependency it may not be able to use. make_plots and to_pydot report what to install when pydot is missing.
