ahh, good to see you did decide to post ....
anyways, i did some searching (i was board .. and waiting to heal (those deer's really hurt)) ... anyways mandrake does NOT have eternal lands in its package list (look at rpmdrake , its mandrakes installer program)
anyways, aparently i was wrong about that rpm thing (sorry), there doest appear to be one, but eternal lands website does have a linux binary (here :
http://www.eternal-lands.com/index.php?content=download ) ... it should work, if it doesn't then you shall need to compile by hand (its rather easy .. until there is a problem)
good luck with it
