There is a version of ARTstor that works in OS X Lion. The version number is the same (3.1.2) but the download page lists one for Lion and one for previous versions of OS X.
The Lion-compatible version of ARTstor is not officially compatible with OS X Mountain Lion but it appears to work correctly. Disabling Gatekeeper just run it the first time may be necessary.
