Update of Homebrew on julia 0.6.1 gives build errors

[tlnagy]

Hey @staticfloat, I see this everytime I try to build Homebrew on Julia 0.6.1

julia> Pkg.build("Homebrew")
INFO: Building Homebrew

Any thoughts?

I was having the same issue. I followed the suggestion from #206 to nuke the repo and add it again and it seems to work now.

Apparently clearing out the repo isn't enough, since the failures are reproducible on Travis? See https://travis-ci.org/JuliaOpt/CoinOptServices.jl/jobs/302334821#L334

This is reproducible from the command line

Nuking the Homebrew package directory indeed fixes the issue. It also installs a newer version of homebrew.

So fyi I followed the instructions here, and it fixed the above issue, but now I'm seeing the same thing as #215.

This error means the ruby, which brew uses, cannot recognize indented here document by <<~ that is introduced at Ruby 2.3. I think the system in which this error occurs has Ruby 2.0 at /usr/bin/ruby and brew uses it.

I propose the following temporary workaround for such situation:

julia> ENV["HOMEBREW_DEVELOPER"] = "1"
julia> ENV["HOMEBREW_RUBY_PATH"] = "YOUR_RUBY_PATH"
julia> Pkg.build("Homebrew")

Setting the two environment variable HOMEBREW_DEVELOPER and HOMEBREW_RUBY_PATH, you can force brew to use the specific ruby. Please replace YOUR_RUBY_PATH with the correct path of ruby >= 2.3. If you use rbenv, it should be like /Users/mrkn/.rbenv/shims/ruby.

Confirmed that the system ruby on OSX is ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin16], at least for 10.12.6.

It'd be really nice to ensure that Homebrew.jl worked without having to install a custom version of ruby.
