Merge upstream ruby-build changes

[charlesbjohnson]

Howdy,

I have several branches lined up for the recent iojs releases (1.0.0 through 1.1.0) that I want to eventually get merged in. However, they fail to build because the current implementation of checksum verification assumes sha1 which is incompatible with the sha256 backed checksums being used for iojs releases. As such, I would need to do some tweaking beyond the typical one-liners I've been adding to share/node-build in order to get the iojs releases to properly build.

Before I embark on any changes that would cause us to further divert from ruby-build, however, I thought it might be worthwhile to pull in the compatible upstream changes/features that have been made in ruby-build. Considering the difference in build versions (201300310 vs 20150130), I think a few things have changed 😛.

What are your thoughts? I'm more than happy to see this process through and make a PR for it, but I just wanted to make sure that you would be receptive to these changes before I spend the time making them. It might also be worth discussing how to handle future upstream changes.

Thanks!

Hey @OiNutter I'm sure you are busy but even a quick 👍 or 👎 would be perfect.

Hi

Yeah, sorry, just not been able to get to even look at some of this stuff. Definitely on board with getting nodenv up to date with the latest rbenv/ruby-build changes but not sure when I'm going to have chance to look at that. If you've got time and are willing to do it and submit a pull request then go for it. I'll try and be a bit sharper and checking it out and responding this time.

I just merged #53 which brings us up to Oct 2013.

And I just opened #54 which brings us to 2014. But #54 needs some work before it can be merged. @charlesbjohnson do you think you could help get the tests correct in #54 so we can continue?

Keeping this open as a tracker, but I'm steadily merging in updates from ruby-build upstream. As of now, we're up to June 2014 v20140524
