Typically, you can use older versions of rsyntaxtextarea.jar with TokenMakerMaker, but just recently I introduced a fairly large (internal) API change, that had the side effect of TMM requiring the latest RSyntaxTextArea from SVN. I didn't really see this as a problem, since if you've pulled TMM from SVN (the only way to get it), you're probably also pulling RSyntaxTextArea and its sister projects as well.
With the upcoming 2.0.7 release, I'm considering releasing a pre-built TokenMakerMaker along with RSTA, AutoComplete, etc. Although it's somewhat limited in features, I think it's a very useful tool that's probably often overlooked because it's not available as a simple download. But until then, it's available from the Subversion repository only.
