At least for recent openstudio versions, DView is bundled with the package - check /usr/local/openstudio-version/bin. It just can't be found easily as /usr/local/openstudio-version/bin isn't in user's path (note that openstudio or OpenStudioApp have symbolic links added to /usr/local/bin, which is usually included inclided in the $PATH variable, so they can be found from the command line).

If in your openstudio version DView isn't there, then another possible option is to download a recent one and use DView bundled with it.
