There is an apt-get package for Mandrake. It is called apt (I thought it was apt4rpm, but a quick urpmf told me differently)
Provided you have set up your urpmi sources with easyurpmi:
http://easyurpmi.zarb.org
urpmi apt
You might be presented with a list, you'll probably have to type in the full filename from that list to get it to install correctly.
