Cairo segfaults on macOS - possibly Homebrew-related?

[cormullion]

(When opening an issue, please ping @staticfloat.)

Cairo has been segfaulting on macOS/Travis, since about March 7th.

Eg https://travis-ci.org/JuliaGraphics/Luxor.jl/jobs/503554126 :

 Building Cairo ───────────→ `~/.julia/packages/Cairo/CXPG1/deps/build.log`
┌ Error: Error building `Cairo`:

└ @ Pkg.Operations /Users/osx/buildbot/slave/package_osx64/build/usr/share/julia/stdlib/v1.0/Pkg/src/Operations.jl:1097

There's a suggestion (JuliaGraphics/Cairo.jl#271 (comment)) that this is probably a brew-related error. (Presumably because the same version of Cairo works on all Linux...).

Elliot, I know you're not working in this area so much these days... Have you found a successor? :) Or do you have any tips on how to tackle it?

Same problem on My Mac (Mojave) occurs even the latest version of Homebrew.jl

@terasakisatoshi Current thinking (JuliaPackaging/BinDeps.jl#397) is that this is a problem with the libraries loaded by Homebrew/Cairo (pango, glib, etc.) so there might be a manual workaround (downloading libraries separately). You could wait until it's fixed, but I don't know if anyone's working on it...
