Reinhard,

I am the owner of the tree and I know (now) the MTPro installation is the
one
fully to be blamed here and not tlmgr.

The problem is that lots of CTAN material is out there recommending/doing
a sudo on their own initiative... and that leaves a LOT of people with
mixed
ownership trees. Yesterday we asked here in Berkeley who has a mixed
ownership tree and 5 out 5 had - and surprisingly because of widely
different
reasons.

But even knowing that tlmgr is not the culprit, it would not hurt to check
before
starting -- it takes less than a second to a check on the whole tree.
