Thanks. :-)
In case anyone is interested, below is a patch against the current centos tar-1.14-9.RHEL4 SRPM.
I've tested it and it seems to do what I wanted.
1. Get the SRPM. 2. rpm -i tar-1.14-9.RHEL4.src.rpm 3. cd /usr/src/redhat/SPEC 4. rpmbuild -bp tar.spec 5. cd ../BUILD/tar-1.14/ 6. patch -p1 < /path/to/patchdir/tar_no_cache.patch 7. ./configure 8. make 9. cp src/tar /usr/local/bin/tar_no_cache
tar_no_cache -c -v -f /dev/st0 .
