I've been yum-enabling some of our RHEl4 machines in the past few days
with (note this is all on *one line* - mail client will stuff up the
line breaks):
rpm -Uvh
ftp://ftp.scientificlinux.org/linux/scientific/46/x86_64/SL/RPMS/yum-2.4.3-2.SL.noarch.rpm
ftp://ftp.scientificlinux.org/linux/scientific/46/x86_64/SL/RPMS/urlgrabber-2.9.6-1.noarch.rpm
ftp://ftp.scientificlinux.org/linux/scientific/46/x86_64/SL/RPMS/python-elementtree-1.2.6-4.x86_64.rpm
ftp://ftp.scientificlinux.org/linux/scientific/46/x86_64/SL/RPMS/python-sqlite-1.1.6-1.x86_64.rpm
ftp://ftp.scientificlinux.org/linux/scientific/46/x86_64/SL/RPMS/sqlite-3.1.2-3.x86_64.rpm
ftp://ftp.scientificlinux.org/linux/scientific/46/x86_64/SL/RPMS/yum-conf-4x-1-7.SL.noarch.rpm

Replace the "46/x86_64/" part with whatever's suitable.
