This is stable/15 server running releng/13.5 poudriere jail.
poudriere itself calls sccache via the sccache-overlay like

# poudriere bulk -j 135R-amd64 -O sccache -f filelist.txt

so it calls (externally) sccache materials built and installed on the host.
So, what you're saying makes sense. 

But, I cannot install sccache for 13.5 on a stable/15 host. I saw nothing
during install that sccache-overlay use must be with the same major freebsd 
version of host and builder.

Removing the -O sccache allows the build to proceed, some 500 or so packages.
Do you think this an sccache{-overlay} problem?
