brew doctor output

Your system is ready to brew.

Verification

• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.

What were you trying to do (and why)?

Trying to install Julia's dependencies, to test a manual build from head.

What happened (include all command output)?

$ brew install --only-dependencies julia
julia: The x86_64 architecture is required for this software.
Error: julia: An unsatisfied requirement failed this build.

What did you expect to happen?

Since I am only asking for dependencies, it should not matter that Julia itself has an arch requirement: it will not be installed.

Step-by-step reproduction instructions (by running brew commands)

$ brew install --only-dependencies julia

Another case with similarly weird output: I've removed the arch requirement in the formula, to bypass the issue, and now:

$ brew install --only-dependencies julia
Error: julia: no bottle available!

All the dependencies have a bottle, so it's not really relevant to complain about julia since it won't be installed.

I can't reproduce your second weird output here. 😕
