Error when using Uglify Node API (with OS X Lion)

[JamesV]

I have started to use UglifyJS, and am very impressed with its
capabilities. I am, however, having a problem with the JavaScript API
for Node. In OS X Lion I get the error below.

I used npm to get Uglify - is that an earlier, broken version? I had
trouble following the instructions for installing it from github, and
am not sure if I am using the version from there or from NPM.

Any help with this would be much appreciated.

You probably figured it out already, but here it is: this happens if you don't pass valid source to parser.parse (e.g. passing `null`, or a byte array won't work -- you need to pass a string that contains the source).
