Hi Jeff,
Yes, my recommendation is to just replace the default version of chuck with the lion executable (that's what I did on my Lion machine).
<excuse> The Chuck + Lion issue is a bit annoying right now, and I'm in a bit of a holding pattern as I decide how to handle chuck support (and cross-platform support) in the next release. </excuse>
Good luck and let me know if you have any other questions/issues!
Rebecca
