 I just compiled on bluewaters and received output
 {{{

 All done !

 Building utilities for simO3

 Creating hdf5_recombiner in /mnt/a/u/sciteam/rhaas/ET_trunk/exe/simO3 from

 with the full (last part of) the log in the attached file.

 So it seems as if we have a race condition in the make system that causes
 it to try and build the utilities twice (in parallel).

 On bluewaters simfactory (which I used) builds Cactus using 16 processes.
