I wonder what is different on your system, since I'm not able to confirm this issue.
That's what I get on two different systems, can you please check your poudriere and make sure you have the latest poudriere installed.
Do you use ports-mgmt/poudriere-devel or ports-mgmt/poudriere?
With poudriere-devel-184.108.40.20651125 I got once an error in a different port since poudriere was cleaning the jail before the build was finished, but this is fixed in the latest version)

This error was produced by poudriere-3.1.9, not a very recent version. It produced various failures on 5 ports out of 800.
I will rerun with the latest version and will let you know.
Anyway if poudriere fails the log is available, perhaps you can find the issue directly there or attach the failed build log.
This is a local issue, not a poudriere one.
I don't know why out of hundreds of packages this one failed.
Closing for now.
