{for what it's worth...} The courtesy binaries for Mac OS X hosted on the gridengine website are apparently built on a 10.2 based Apple machine. Ever since the project started officially posting the binaries I've had good success using them with the exception being I could rarely get the X11 GUI application 'qmon' to launch successfully. I sat down today with a fresh CVS checkout of the sge-6.0beta2 source code and managed to get everything built, installed and running on a 10.3.3 powerbook. The obligatory screenshot for this sort of thing can be found at http://bioteam.net/dag/sge-6-screenshot.jpg The notes kept during this process have been placed online at: http://bioteam.net/dag/sge-6beta2-osx-buildnotes.html Hope this helps someone or at least saves a bit of time!
