# until autoconf is set up, here are the options i understand:
#
#  darwin=yes    -- build on darwin
#  fuse=no       -- don't build anything requiring FUSE
#  mpi=no        -- don't build newsyn (require MPI)
#  use_ccpp=yes  -- use Common C++ for buffer.h reference counting
#  want_bdb=yes  -- build berkelydb objectstore
# 

# mpicxx must be on your path to build newsyn.  
#  on googoo, this means that /usr/local/mpich2-1.0.2/bin must be on your path.
#  on issdm, it's /usr/local/mpich2/bin.
