Problem using SmartTabs in Emacs

I'm trying to use smarttabs.el from https://gis开发者_如何学运维t.github.com/188961 in latest emacs-dev (bzr). When trying to compile or load it I get the error:

smarttabs.el:54:1:Error: Don't know how to make a localized variable an alias

which is completely new to me. How do I correct this?

Also see http://www.emacswiki.org/emacs/SmartTabs for package explanation.

The error message is trying to say that defvaralias (used in the smart-tabs-advice macro) doesn't do what jacius thinks it does. But I'm not quite sure what he thinks it does, so I'm not sure how to fix it. Try reporting the error to him.
