Thank you both for picking up some of the points,
where as my actual concern was, that PD & externals should be easier accesable by the not-so-deep invovlved public. The other points where merely suggestions, so you can ignore them if they are that appart from reality.
But thank you Mathieu for bringing up OS X, i understand now that this is probably the core of my problems. I will try to fix a linux here and look how it goes.
