Wes McKinney closed ARROW-4023.
-------------------------------
    Resolution: Not A Problem

The macOS builds are taking 27 and 11 minutes now respectively, so we can revisit when build times get longer

>             Project: Apache Arrow
>          Issue Type: Improvement
>          Components: C++ - Gandiva
>            Reporter: Wes McKinney
>            Priority: Major
>             Fix For: 0.13.0

> I noticed that installing the toolchain and building Gandiva on macOS in Travis CI took over 30 minutes in a recent build
> https://travis-ci.org/apache/arrow/jobs/467681438#L113
> The overall build took ~45 minutes, so this build isn't far away from timing out. 
> It seems that this could be partly caused by installing some heavy dependencies like llvmdev from conda-forge. conda-forge has been getting a lot slower lately.
> We should see if using defaults to install llvmdev will improve build times, or if there's a faster way to get the toolchain bootstrapped.
