>Description:
I noticed a few changed owners/groups in the daily setuid mail, e.g.:
-2249360 -rwxr-sr-x  1 games   games       1811506 Nov  9 23:34:39 2012 /usr/local/lib/nethack/nethack
+2249360 -rwxr-sr-x  1 root    wheel       1811506 Nov  9 23:34:39 2012 /usr/local/lib/nethack/nethack

The first part of the post-install of openvpn-2.3.0_2 does 

.for i in lib sbin
   (cd ${_stagedir}${PREFIX}/${i} && ${COPYTREE_BIN} \* ${PREFIX}/${i}/)
.endfor

which results (among other commands) in:
chown -R root:wheel /usr/local/lib
chown -R root:wheel /usr/local/sbin

Files from virtualbox-ose and lsof were also affected.
>How-To-Repeat:
Have some files with owner:group != root:wheel in /usr/local/{sbin,lib} and install security/openvpn-2.3.0_2 .

The corresponding output is:
===> Installing rc.d startup script(s)
/bin/mkdir -p /usr/local/lib /usr/local/sbin /usr/local/include /usr/local/man
(cd /usr/ports/security/openvpn/work/instage/usr/local/lib && /bin/sh -c '(/usr/bin/find -d $0 $2 | /usr/bin/cpio -dumpl $1 >/dev/null  2>&1) &&  /usr/sbin/chown -R root:wheel $1 &&  /usr/bin/find -d $0 $2 -type d -exec chmod 755 $1/{} \; &&  /usr/bin/find -d $0 $2 -type f -exec chmod 555 $1/{} \;' -- \* /usr/local/lib/)
(cd /usr/ports/security/openvpn/work/instage/usr/local/sbin && /bin/sh -c '(/usr/bin/find -d $0 $2 | /usr/bin/cpio -dumpl $1 >/dev/null  2>&1) &&  /usr/sbin/chown -R root:wheel $1 &&  /usr/bin/find -d $0 $2 -type d -exec chmod 755 $1/{} \; &&  /usr/bin/find -d $0 $2 -type f -exec chmod 555 $1/{} \;' -- \* /usr/local/sbin/)
