Some Mageia package depend on packages older than those installed...

Hello all, I've been trying again to install TDE on Mageia 3 (following the install instructions). Most of it seems OK, but the install fails with a message saying some packages can't be installed because they depend on packages older than those installed. The packages in question are trinity-perld-dcop, trinity-tdebindings and trinity-desktop. However, I've noticed that links, when installing software from Mageia, contain a directory "cauldron", and uname -a returns an "mga4" element. I associate "cauldron" with a development version, am I right? So could it be that I somehow got a development version of Mageia? The md5 hash of my DVD is not the same as that given on the mageia site ?!? I am re-downloading a fresh image from Mageia 3 now, but if anyone has more knowledge about Mageia than me, I'd be happy for any information about the version I should install for TDE... Regards, Thierry
