[julia-users] Re: How to fix package after breaking change in 0.4?

[Seth]

This isn't a drop-in replacement:

ERROR: LoadError: MethodError: `_make_simple_undirected_graph` has no 
method matching _make_simple_undirected_graph(::Int64, ::Array{(Int64,Int64
),1})

I'm calling it like so:

function PetersenGraph()
    e = [
        (1, 2), (1, 5), (1, 6),
        (2, 3), (2, 7),
        (3, 4), (3, 8),
        (4, 5), (4, 9),
        (5, 10),
        (6, 8), (6, 9),
        (7, 9), (7, 10),
        (8, 10)
    ]
    return _make_simple_undirected_graph(10,e)
end
