[netCDF #RUE-876772]: Netcdf/opendap build

Kevin,

The latest snapshot is available from the link on the netCDF home page

   http://www.unidata.ucar.edu/netcdf/

labeled "netCDF snapshot release", which is not all that easy to see amid
all the links on that page :-).  It points to

   ftp://ftp.unidata.ucar.edu/pub/netcdf/snapshot/netcdf-4-daily.tar.gz

which is actually the latest distribution that built and passed all the tests
successfully on a single Linux reference platform we use here.  So if we've 
been introducing new bugs at a very high rate, it may actually be several days
old, until we get them all fixed and get a successful build.
