using npm debug module breaks build (overriding any property on process.env)

I'm getting this error:

I've tracked this odd bug down to these lines in the debug package

https://github.com/visionmedia/debug/blob/9f4f8f59ba745166b0c014a61c76de5e73d4841a/src/node.js#L199-L207

My current workaround is to just use a different debug module which doesn't mess with process.env

Any other ideas?
