im not positive, but if your compile wasnt working i think ./configure would throw errors would it? or make...either one, you got gcc? thats what i had to install as most new distro's (my experiance with suse) dont actually come with a compiler???
what id do is go here Easy URPMI
and select the nearest mirror for "main", "contrib" and "updates" then click "proceed to step 3" and then execute the commands it shows one by one as root in your console, then go into "install packages" on your drake, then make sure you have libqt, libpng, gcc and xfree86-devel (make sure its the one for your xfree86, the way i found this out was by going into control centre for KDE and going information -> X-server). When you do all that it should install some other packages too.
As i said, this might be REALLY bad directions but it worked for me so hey why not give it a try? besides you may as well add those sources to the mandrake RPM installer as they can give you access to loads more packages than you have now (i only installed CD 1 so i had VERY limited packages)
anyway try it out, let me know how it goes!
