Building VegaLite fails on v5.3.0

[asinghvi17]

When trying to build VegaLite on MacOS (latest version), this happens:

However, running

curl -f -o /Users/anshul/.julia/packages/VegaLite/Sl5pu/deps/lib/vega-lite-schema.json -L https://vega.github.io/schema/vega-lite/v2.6.0.json

in bash works fine.

I got VegaLite to build by manually executing the failed command whenever there was an error - it seems LibCURL was not liking what seemed to be a perfectly valid command.
