Virtualization only works on Intel Macs.
On PPC Macs emulation works perfectly. The most popular emulator for PPC Macs used to be Connectix Virtual PC (now a Microsoft product). Other emulators are discussed here: http://www.macwindows.com/pcemul.html
Same problem here. I tried using ./ also. The error message is still "command not found". Does anyone have the source code available so I can try to compile it for my intel mac?
