I guess there is a different QCAD available now. This is the one I used: http://www.free-downloads-center.com...12-5-2362.html

Looks like P-CAD is obsoleted as well: http://www.altium.com/community/down...gacy_p-cad.cfm

Oh well. Sorry I can't help you more, but I did find the Linux packages I was thinking of: Kicad and Geda.
