Strange, although I already made them executable, they lost it again, made them executable again and now it works.
So still to find out, how to update in svn.
[EDIT]
for 1 of the 2 svn commit thinks something has changed, but I don't know how to write the comment for it (yes I don't know vi, and to be honest, what i see from it now makes me angry) :-( [so I issued svn commit]
[EDIT2] : kdesvn helped me out : so libfinder done [well I doubt it, in another view, I did the svn update, and it is still not executable, or should a new clean checkout be done ??]
[EDIT3] : will give up for now, pff, other time better luck ;-)
