It looks like there is a problem in the port itself. It appears to be trying to move file(s) that do not exist during the port installation.
You can click on any file on the build server, then open the "build.log" to see what the exact error(s) are. The error is usually right near the bottom of the file.
You might want to try contacting the port maintainer to see if this is a known issue.
