PyDev installation

I am following Ron Smith’s 15 June 2004 article Python development with Eclipse and Ant from IBM developerWorks. The first step is to install the PyDev plugin which is available at Eclipse update site

First problem is that when I try to call the python interpreter to run the test I get a launch error. Don’t know if this is an Eclipse, PyDev or Python problem. Launch configuration seems ok! I checked the pydev user forum and this is a known problem and we await a fix.
