 The log says:

 {{{
 :debug:activate Backtrace: Image error: /Applications/MacPorts/Python
 2.7/IDLE.app/Contents/Info.plist already exists and does not belong to a
 registered port.  Unable to activate port python27. Use 'port -f activate
 python27' to force the activation.
 }}}

 Why does this file already exist on your system, if it did not come from
 MacPorts?
