Description

Oddly, it looks like the formula builds successfully (https://travis-ci.org/ursa-labs/crossbow/builds/631795636#L3698)

🍺  /usr/local/Cellar/apache-arrow/HEAD-096c78c: 366 files, 57.5MB, built in 9 minutes 46 seconds

But it exits with status 1. AFAICT the error is here: https://travis-ci.org/ursa-labs/crossbow/builds/631795636#L1745
