Update:

(sunpoet@ I hope you don't mind my fixing your port)

- we've had an older bug report from 2020-04-10,
  https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=245514

- Franco Fichtner had provided a similar fix as of 2020-04-29,
  the maintainer (sunpoet@, on Cc:) hadn't responded since,
  so I was permitted to commit; fix committed in r535475.
  You can tell that you have the current version if after update
  you can see a ${CHMOD} near pre-test: at the end of
  net/librsync/Makefile.

- upstream bug report filed against what I believe to be the culprit,
  the upstream file cmake/FindPOPT.cmake seems to be broken
  in case pkgconf or pkg-config or equivalent are found
  during "make configure" (i. e. while cmake is running).

HTH.

If not, please reopen and follow up on Bug 245514 above.
