"illegal hardware instruction" on install command

[gutierlf]

I've tried installing Elm 0.18.0 via npm and via the Mac installer. In both cases, I can't get elm-package install to download packages for me.

> mkdir test-example
> cd test-example
> elm-package install
Some new packages are needed. Here is the upgrade plan.

  Install:
    elm-lang/core 5.1.1
    elm-lang/html 2.0.0
    elm-lang/virtual-dom 2.0.4

Do you approve of this plan? [Y/n] Y

[1]    65368 illegal hardware instruction  elm-package install

(That's the error message when using the version installed via the Mac installer. When using the npm-installed version, there was no illegal hardware instruction error; it was just completely silent.)

@agrafix's python script found in #115 does work and allows me to install packages one-by-one, but I don't know how that script is different than what elm-package install does.

My configuration:
OS X 10.11.6
2.2 GHz Intel Core 2 Duo
Elm 0.18.0

Thanks for the issue! Make sure it satisfies this checklist. My human colleagues will appreciate it!

Here is what to expect next, and if anyone wants to comment, keep these things in mind.

Can you say more about your system? Is there anything notable? Any odd hardware? Any weird configuration?

I would expect to hear much more about this issue if lots of folks were seeing it, so I strongly suspect there is something unlikely about your system.

Thanks for following up on this!

This also surprised me initially, but then when I found the other issues that I mentioned above, including a python script workaround, I thought, "well maybe this old bug just popped up again."

In any case, I'll try to answer your question about my configuration. I'm only answering from memory right now because I'm not in front of my computer, and I'll add more later if I find something. However, I don't think I'm doing anything weird with this machine. No additional hardware. That said, it's an old machine that I just found and wiped clean a couple months before trying out Elm. Because it's not very powerful, I've tried to keep it pretty vanilla, with few additional apps or frameworks installed.

Are there any specific parts of my configuration that you're suspicious about where I might look more carefully? Or anything I can do to generate more verbose log information that might prove more useful in getting to the bottom of this?
