Just had a mission upgrading to v4.4.2.
RHEL4 was setup using basic install and was not very easy to do.. kept winging about things not being found therefor ./configure kept failing.
For all peeps information, since it took me ages to work out. As each error comes up is to search for the package it complans about and install/upgrade it. Dependancies are a killer but after about 2 solid hours of upgrading packages and installing software it started working.
RHN is good for the package sources for these kinds of things.
I prob could have found the RPM for 4.4.2 but its far to easy and not very fun doing it like that so 442 is now running.
