Poudriere staging failure for rubygem-racc 1.8.0

Hi everyone,

I’m trying to get a local Poudriere builder going, using a 13.2 jail, which I do know is out of support at this point, to build packages for a collection of local jails that, at least for the time being, need to remain on 13.2 themselves (hosted on TrueNAS CORE —yeah, don’t get me started!-- which hasn’t yet made the jump to FreeBSD 13.3).

Everything is working fine so far, other than rubygem-racc 1.8.0 failing at the staging step with a staging violation:

=>> Checking for staging violations... done
=>> Error: Filesystem touched during stage (files must install to ${STAGEDIR}):
extra: var/cache/ccache

This is with a latest ports tree last updated just last night. If anyone could offer any help, either to solve the problem directly or hinting where I should even start looking, I’d most appreciate it!

Thanks,
