Tried on v0.3.5 - works fine after I added a "partials" parameter to boil config on maptail.js line 39.
Otherwise boil.js fails to normalize the path because it's passing an undefined value and path.normalize tries to access "charAt" function of the string.
Can you be more specific? This is the first time I've tried to use node.js for anything and am very unfamiliar with the environment. I'm running into the charAt problem though, so I think your fix will be my fix.
