[cobalt-developers] rpms

["Road Runner" <rshepard@xxxxxxxxxxxxx>]

i am trying to install a "postfix" rpm
(postfix-20010228_pl03release-7rh6x.i386.rpm). This is supposed to be a
release that runs on redhat linux 6.2. we are running a cobalt raq4 with
cobalt linux (kernal 2.214). i was told that this is nearly true blue redhat
linux 6.2 and that softweare installation via rpms would work. i transferred
the rpm in binary mode

i get the following error message:


rpm -Uvh /etc/postfix-20010228_pl03release-7rh6x.i386.rpm
only packages with major numbers <= 3 are supported by this version of RPM
error: postfix-20010228_pl03release-7rh6x.i386.rpm cannot be installed

is there another version of the rpm program that will work ?
