OK, but that was not clear from Norbert's message.  He wrote only of the 
first step (the testing of /usr/local for writeability), which in your 
case would fail.  He did not go in to enumerate the other steps you 
mention, so it seemed from his earlier message that the installer should 
have reported-and-aborted and this point.
