More cairo debugging. Pkg.status() shows both Cairo and Gadfly as installed. But, trying to use Cairo:
*julia> **using Gadfly* *INFO: Precompiling module Gadfly...* ERROR: LoadError: could not open file /Users/lewislevinmbr/.julia/v0.4/Cairo/src/../deps/deps.jl Note the load error. Well, there is no such deps.jl anywhere in the Cairo package tree. So, of course it can't be loaded. I also installed cairo, successfully, with homebew outside of julia, but that doesn't help julia in the slightest. This stuff seems rather fragile and the source of many problems.
