Here is a patch that adds the missing =back to get it to compile.

I'll leave it to the maintainer to determine whether /usr/bin/pod2man is actually the intended tool here. Probably it should be using ${prefix}/bin/pod2man-5.16 instead. But that would be another issue.

See #50111. Fixed by updating in r144335 (maintainer timeout).
