This error is getting old, but here it is again: I upgraded my Mac to the new OSX Sierra, and I am now seeing the error

_jl_libcairo not defined

with IJulia on Julia v0.5.

Specifically, the following command works at the Julia prompt but produces the error _jl_libcairo not defined in IJulia:

using Cairo, Gadfly
plot(x=rand(4), y=rand(4), Geom.point)

Is there a recommended fix?
