[antlr-interest] Q: Eclipse AntlrDT plugin - cannot open file

[Austin Hastings]

I was using the wrong DLTK. Now I'm using the right one, and I have the 
same problem.

I unpacked the dltk zip into the eclipse directory (actually, into .., 
since the zip included an "eclipse" node). I re-downloaded the antlrdt. 
Unpacked it into eclipse. Still the same exception.
Does antlrdt bundle the antlr libraries?
