Comment:

 If you cannot explain why this file was already there when MacPorts did
 not install it, then perhaps other files were also installed into the
 MacPorts prefix by something other than MacPorts (perhaps by some
 installer you ran?) and if so you would likely run into this problem again
 in the future with other ports. You may need to uninstall MacPorts and all
 ports and then reinstall the ports you want to get back to a consistent
 state. If you can remember running and installer that put this file there,
 then you should advise whoever distributed that installer that they should
 change where their installer installs files so that it does not conflict
 with MacPorts.
