Today I did a git pull and tried to build ET dev. It crashed with references to hdf5 as is shown in the pastebin:  http://pastebin.com/EdqqhdE0 .  Note that I am using the HDF5_DIR = BUILD option and have checked that mpi and gcc are compatible (the versions from macports).  I have removed hdf5 from active ports some time ago. So can developers please let me know what might be going on?
