Same issue with tcpdump from ports, looks like its at the same version.

$ which tcpdump
/usr/sbin/tcpdump

$ /usr/sbin/tcpdump --version
tcpdump version 4.9.2
libpcap version 1.8.1
OpenSSL 1.0.2n-freebsd  7 Dec 2017

$ /usr/local/sbin/tcpdump --version
tcpdump version 4.9.2
libpcap version 1.8.1
OpenSSL 1.0.2n-freebsd  7 Dec 2017

Ports version is using libpcap from ports too.

$ ldd /usr/sbin/tcpdump
/usr/sbin/tcpdump:
	libpcap.so.8 =3D> /lib/libpcap.so.8 (0x800908000)
	libcasper.so.0 =3D> /lib/libcasper.so.0 (0x800b65000)
