I'm on a linux (x86_64) machine without any antivirus software or 
similar … to be more verbose, the following packages are reported every 
tlmgr run:

skipping forcibly removed package amscls  (no more now)
skipping forcibly removed package chemnum
skipping forcibly removed package context
skipping forcibly removed package cyrillic
skipping forcibly removed package othelloboard
skipping forcibly removed package pst-rubans

Should I just --reinstall them and forget about it?

cheers
Arno
