during initialization of module GraphViz

julia>

Reproduce the failure with julia --project=. and using GraphViz. Start in src/GraphViz.jl at lines 38 and 206, where the libgvc error occurs during initialization. Done means the module loads without the reported UndefVarError on the shown Julia version.
