This failed on a 32-bit Debian install in VirtualBox with a 64-bit Windows Vista host with Xmingw as the X server though SSH via PuTTY. So if you were thinking about trying on that, don't bother. ;PHmm, Maybe it's failed because you're running it on Virtual Environment. Some components might not works in VirtualBox.
Next time I have to do computer maintenance and data's backing up or something, I'll try this out.
