Soeren,
It definately looks like you have an installation problem.
I did not pull down the giant eclipse with 70mb with everything. Do I need it all? Did not seem to me like source code and extra documentation would matter.
Yes, you really do need everything. In addition to the things you mention, the full distribution of Eclipse also includes the PDE and a few other things that MyEclipse makes use of. The full distribution is the only one that will really work.
At this point I’d suggest that you uninstall MyEclipse, uninstall Eclipse, and then download and install the full Eclipse distribution for Linux. At that point, before you run the MyEclipse installer again, set the environment variable LAX_DEBUG=1. This will cause the installer to spew out lots of output during the installation process, which may be needed in case you do have an installation issue. If you don’t have a problem, it’s just a lot of extra output we won’t need. 🙂
