I'm trying to install Antlr IDE with Aptana and I got this error log from the Update Manager. What exactly is going on?
Cannot complete the install because of a conflicting dependency.

From what I see, ANTLR IDE is based on Eclipse 3.7 (Indigo), while Aptana Studio stand-alone is shipped with Eclipse 3.6. That's probably the reason you are getting this installation issue.
You can install Aptana Studio as a plugin on top of Eclipse 3.7, and then install ANTLR IDE as well.
Checkout the http://preview.appcelerator.com/studio/ (Aptana Studio tab) for the Studio's update site.
