bad interaction with @pyimport

[ggggggggg]

GraphViz doesn't seem to work on my system if I do @pyimport before trying to it. Below I've included a minimal example and output. If I make the GraphViz calls before the @pyimport, then future GraphViz calls work. I can probably use that as a work around for now.

I can't reproduce the error on JuliaBox, so it may be OSX specific?

Not sure where this issue actually belong, only posted it here though.

using GraphViz
using Graphs
using PyCall

@pyimport scipy.signal as scipysignal
g = simple_wheel_graph(6)

dot = to_dot(g)
gviz = GraphViz.Graph(dot)
println("Calling layout!")
GraphViz.layout!(gviz,engine="dot")
println("Starting file write.")
open("test.svg","w") do f 
       GraphViz.writemime(f, MIME"image/svg+xml"(),gviz)
end #do

output:

Doesn't happen with the jll based onee.
