The rpm database is in the format of C6, so the C5 programs can't read it!

perhaps if you kept the rpms that were installed by yum, you could rpm -i --justdb *.rpm within your chroot.

If necessary first remove the rpm database and rpm --initdb or some such.

Interesting idea!

yum --setopt=keepcache=1 --disablerepo=* --enablerepo=c5* -y --installroot=$ROOT install $rpms

# Fix up RPM database rm $ROOT/var/lib/rpm/* chroot $ROOT /bin/rpm --initdb chroot $ROOT /bin/rpm -i --justdb '/var/cache/yum/*/packages/*.rpm'

And y'know what? it worked!

Very good idea. Thanks!
