/work/00507/eschnett/Cvanilla/arrangements/PITTNullCode/SphericalHarmonicDecomp/src/ExtractMetric.cc(38): catastrophic error: cannot open source file "hdf5.h"

  #include <hdf5.h>

It seems that HDF5's "detect.sh" does not work correctly. Cactus seems to make no attempt to build HDF5.

For the time being, I've reverted the recent changes to thorn HDF5.
