# RHEL/CentOS Stream 7 and 8 ship perl-FindBin / perl-IPC-Cmd only
# inside modular Perl streams that COPR mock filters out by default,
# and COPR builders have no network access to `dnf module enable`.
# The CI workflow vendors the .pm files into this tarball; the build
# stanza extracts it and points PERL5LIB at the result so the build
# sees the modules regardless of distro.
