I'm not sure if the following might help or not.

In my (official pkgbase distribution) context:

# uname -apKU
FreeBSD 7950X3D-ZFS 16.0-CURRENT FreeBSD 16.0-CURRENT main-n281133-2241cd10d6e0 GENERIC-NODEBUG amd64 amd64 1600001 1600001

# grep setgroups `grep -rl FBSD_1.8 /usr/src/`
/usr/src/lib/libsys/Symbol.sys.map:	setgroups;

But libsys was new as of 15. The FBSD_1.8 status
for setgroups was as of:

So, the code referencing Undefined symbol "setgroups@FBSD_1.8"
is not from 13.5-RELEASE-p5 but from 15+ yet was executing in
a context where the above had not been established in libsys
-- if I understand right. There might not even be a libsys
in that context.

So: in some way an inappropriate mix of vintages seems to
be in use.

Based on the messages, it appears that /overlays/sccache/bin/sccache
has or leads to loading something that the: "setgroups@FBSD_1.8"
reference. It possibly needs to be built for 13.5-RELEASE-p5 . That
would have no "setgroups@FBSD_1.8" reference to complain about.
