I get IBM WSWB drivers, which is IBM repackage of Eclipse 2.1.1 drivers.
The problem is the hyades plugins are all being distributed with the
.classpath, .project, and build.properties files still in them, though
they are binary plugins for distribution. This messes up PDE. It thinks
they are source plugins instead and it doesn't hook them in and it
breaks things because of this.
