As of just a minute ago, I’ve committed a portfile for VW and for ASP in their respective code repositories. The ASP one doesn’t support ISIS or point2mesh. It’s only good for performing stereo on pinhole sessions (MER/Personal Robots) or DG sessions (Digital Globe). I hope that eventually Macports will accept them into their distribution as vw-devel and asp-devel. Until that day, you can use these port files manually using these instructions.
