Shared object "libnetgraph.so.4" not found, required by "netstat"

[tech-lists]

Hi,

I'm getting this error in my daily reports:

ld-elf.so.1: Shared object "libnetgraph.so.4" not found, required by "netstat"

seems to hapen when daily cron runs network interface totals.

This is a freebsd bhyve vm running on a freebsd host:

vm: FreeBSD 12.1-RELEASE-p3 GENERIC  amd64

# freebsd-version -kru
12.1-RELEASE-p3
12.1-RELEASE-p3
12.1-RELEASE-p4

it's kept up-to-date with freebsd-update. The messages I get from
freebsd-update are a little odd:

# freebsd-update fetch
src component not installed, skipped
Looking up update.FreeBSD.org mirrors... 3 mirrors found.
Fetching metadata signature for 12.1-RELEASE from update1.freebsd.org... done.
Fetching metadata index... done.
Inspecting system... done.
Preparing to download files... done.

No updates needed to update system to 12.1-RELEASE-p4.
# freebsd-update install
src component not installed, skipped
No updates are available to install.
Run '/usr/sbin/freebsd-update fetch' first.

I thought netgraph etc would be taken care of by freebsd-update? How can I
fix?

thanks,
