As a little update: I tried to install the context package from 
http://www.pragma-ade.com/context/cont-tmf.zip
into /sw/share/ of the fink distribution both by replacing the 
corresponding directories and by adding the files
into the corresponding directories. Both approaches break the context 
installation. For those interested, the log file
is below.

I give up for today .
Matthias

btw: Somebody with first name Helmut sent me a direct reply, asking 
about rounded corners. Tried that too
without luck. I can't reply to Helmut directly, as his email has my own 
address as the only return address.
Scary.
