That's not a MacPorts package. You are unlikely to find much help from 
this mailing list.

You should do that.

The home site for that software appears to be

MacPorts ports avoid installing anything in either of those directories. 
With very few exceptions, MacPorts installs software under /opt/local/ 
and not in any standard macOS directories to avoid entanglement with 
system software.

That is very strange. You should contact the developer about that, and 
find out if the package is intended to install files owned by 'macports' 
or if that is some sort of accident. It is possible for software to 
install itself under a numeric user ID that accidentally collides with 
the macports user.

'sudo chown <your username> <file or folder name>' should do the job.

Whether that's a solution to your problem or just a way to make it 
worse, I have no idea.
