Are you using the eclipse version of ant or your ant home? I'd try going into eclipse: Window>Preferences>Ant>Runtime, click on the Ant Home... button and point it to your external ant home. This should make eclipse use your installed ant (and it's lib folder) instead of it's built-in version of ant.
