I am afraid that Coreldraw Graphics Suite is not available for OSX operating systems, no matter what the version is. It was released some time ago but the application was unusable and it was discontinued soon. But you have an alternative to this issue: use Lion's feature Bootcamp and emulate a Windows operating system (Windows 7) and then install CoreDRAW for Windows and you'll have a working version of CorelDRAW on your Mac.
