Incompatibe w/ current git Node.js because 'sys' is renamed to 'util'

I just git cloned node.js and socket.io for node,
and see this error message:

$ sudo make
./support/expresso/bin/expresso -I lib tests/*.js
The 'sys' module is now called 'util'. It should have a similar interface.

Here's how I fixed it short term:

find -type f | xargs grep "'sys'" -l
| xargs sed -i "s/\bsys\b/util/g"

find -type f | grep js$ | xargs grep "\bsys\b" -l
| "s/\bsys.(debug|error|inherits|inspect|log)\b/util.\1/g"
