hm that most likely means you have an install without PDE and somehow PDE could not be resolved? What is the base install you start from?

well yes - but that one normally has the update-sites configured so it should have resolved PDE for you

I did a fresh install a month ago and everything else works except I still can't install the e(fx)clipse.
I just tried again and this is the message:
