This happens when 'port activate' finds something unexpected. For
example, assume /opt/local/foo is a symlink to another directory. Now
port tries to activate the file /opt/local/foo/bar, but it can't do that
because /opt/local/foo is not a directory.

I think there is some problem with the python25 framework port. I can 
reproduce the message here and will see if I can find a solution.
