 I don't know what else to tell you. That is not a log from a clean
 attempt. Do you see this line in that log?

 {{{

 That means you have not cleaned this port since before that date. Cleaning
 the port and trying again will work around the bug.


 > There's nothing critical on this system. I'm happy to remove MP and redo
 MP installation and try again. Is there a best command for that?

 If you are running into issues like the one you reported above where a
 file is already in the MacPorts prefix, but MacPorts doesn't think it put
 it there, you could be in a situation where some outside software
 installer has put files into the MacPorts prefix, which can interfere not
 only with you trying to install the same software via MacPorts later but
 can also cause other port builds to be subtly incorrect when they find
 dependencies that weren't expected to be there. Following the
 uninstallation instructions including removing /opt/local and then
 starting over should ensure that you'll avoid such problems.
