EPEERINVALID

on `npm install`

```
npm ERR! node v4.1.1
npm ERR! npm v2.14.4
npm ERR! code EPEERINVALID

npm ERR! peerinvalid The package react@15.0.0-rc.2 does not satisfy its siblings' peerDependencies requirements!
npm ERR! peerinvalid Peer newforms@0.12.1 wants react@>=0.13.0
npm ERR! peerinvalid Peer react-dom@15.0.0-rc.2 wants react@^15.0.0-rc.2
```

No files or tests are named. Start by reproducing npm install with the reported Node, npm, React, react-dom, and newforms versions, then inspect the dependency declarations; done means installation no longer reports EPEERINVALID.
