You can clone with
HTTPS or Subversion.
I had to rewrite:
Script = process.binding('evals').Script
Script = process.binding('evals').NodeScript
in shovel.js (line 10) otherwise Script is undefined and execution fails on line 38.
What version of node are you using?
cloned from github
I'll update the source to try both.
Fixed in 72bd531 (aka version 0.8.0).
