gyp ERR! node -v v6.0.0

Installation of the module with the above versions produces the error message below:

upgrading nan fixes installation error with newer versions of v8. npm test completes successfully on all 43 tests.

I also tested installation and running tests with the following versions successfully:

• 5.10.1
• 5.6.0
• 4.4.2
• 4.2.2
• 0.12.5

It is worth noting that installation fails with node 5.0.0 (which does not currently seem to be the case), and the tests fail with node 0.10.43 (as they currently do).

Thanks Norman. I went through and brought all dependencies up to date. Any reason why you chose 2.2.1 instead of the newest version 2.3.2?

@xorbit at the time I created the PR 2.2.1 was the latest available. It looks like they bumped to 2.3.x around the same time (https://github.com/nodejs/nan/commit/7a84fbba317aaad47a024971e984efb02d356313). Thanks for updating!
