Rayson announced a new release of Open Grid Scheduler. But the announcement does not yet have binaries or source! I was impatient and checked out the latest SVN from the sourceforge page. I ended up with revision 70.
svn co https://gridscheduler.svn.sourceforge.net/svnroot/gridscheduler gridscheduler
On a stock Ubuntu 11.04 box (well, with build-essential installed) I only had to install libpam0g-dev and also download the latest hwloc release from the official hwloc page. I untarred the hwloc code into 3rdparty/hwloc and modified the aimk.site to update the version number for hwloc.
After that, following the official instructions worked just fine, though I did also add “-no-qmon” to each aimk line.
