I built the Einstein Toolkit thorns on a series of machines with different operating systems, including many TeraGrid, LONI, and DOE systems. For this I had to correct or update several SimFactory entries as well as build scripts in ExternalThorns.
I have just committed these changes in the hope that these help portability. Please report any problems you may encounter.
For the record: I tested on abe, bethe, bluedawg, bd, bp, carver, damiana, ducky, eric, franklin, hopper, kraken, lacumba, lincoln, lonestar, louie, neptune, numrel02, numrel05, numrel06, numrel07, numrel09, oliver, painter, pelican, philip, poseidon, queenbee, ranger, redshift, surveyor, tezpur, vip, and zeke. There is a known problem on bd that I reported to the administrators, and a strange error on abe and lincoln that I hope will go away on its own.
