I'm not seeing this with either the sudo-1.9.17p1 binary package from 11.0_2025Q3
or with sudo-1.9.17p2 built from sources:

```
$ head ~/tmp/sudo.config.log 
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by sudo configure 1.9.17p2, which was
generated by GNU Autoconf 2.72.  Invocation command line was

  $ ../sudo-1.9.17p2/configure --prefix=/tmp/S --sysconfdir=/usr/pkg/etc --disable-intercept --disable-root-mailer --with-ignore-dot --with-rundir=/var/run/sudo --with-logpath=/var/log/sudo.log --with-secure-path-value=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/pkg/sbin:/usr/pkg/bin --enable-pie --with-env-editor --with-tty-tickets --enable-env-debug --with-pam=no --without-pam

1. Can you run the `checkoldver' script to see if you have any old library
   versions lying around?

   /usr/src/lib/checkoldver /lib /lib/i386 /usr/lib /usr/lib/i386 /usr/X11R7/lib

   then move the old files away (note that precompiled pkgsrc binaries may still
   need them!).

2. Run (as root):

   ldd /usr/pkg/bin/sudo
   ldd /usr/pkg/lib/sudo/*.so

   to see if sudo ends up using 2 different versions of the same library.

3. Remove any (corrupted) timestamp file just to be safe (also as root):

   rm -v /var/run/sudo/ts/*
