I asked on twitter, pointing to this gist:
https://gist.github.com/jrburke/9101268

So the right invocation might be:

```
npm install --ignore-scripts foo
# later
npm install
```

It looks like there might be some building happening on the --ignore-scripts step, but at least on a local test, the build step seemed to run again when doing the npm install later after the --ignore-scripts call.
