hey man, i'm a linuxnoob myself but i understand a bit of what you need to do.
you're gonna need to download the source for the rpm package and compile it yourself. these files are generally gonna be in a <filename.tar.gz> or <filename.tar.bz> or something like that. basically you can use the wget command to grab it off the net. what i do is find the file using internet explorer on my windows box and hover my mouse over the link that initiates the download, look at it in the bottom left corner of the internet explorer and type that url using the wget command in the linux box.
i.e. wget http://www.redhat.com/downloads.what...isufind.tar.gz
after u get it you'll have to unzip it and then untarball it or whatever the terminology is. get to the next step and post here if you get stuck.
from one noob to another i hope this helps
