Unfortunately the old commits contain issues that cause me issues while using Socket.IO. How can we go about getting the latest builds to work? I'm on CentOS 5.

I fetched latest upstream changes and nodejs compiled cleanly now
# node -v
v0.3.0-pre

Thanks lamnk. How do I go about getting v0.3.0-pre? I can't see to find it anywhere.
