Comment (by kencu):

 This exact error comes up every few years in random ports. On one
 occasion, the user had stuff installed in `/usr/local` from `homebrew`,
 and it was thought that might be the cause.

 On the other occasions, nobody seems to have been able to figure out what
 the issue was. It is not a reproducible error.

 Best I can suggest to you is to look in `/opt/local/var/macports/build/`
 and see if there are any partially-completed builds in there. If there
 are, `sudo port clean` them until that directory is empty. Then restart
 your system to completely reset everything, and try that build again.
