I made a premature announcement about this a day or so ago, but I think
the new patches are working. You can get these via update_amber, or by simply
re-running cmake. Then recompile. Look for update.6 for AmberTools, and
update.2 for Amber.

"There's many a slip....", so let us know if you see things that don't seem
