[netCDF #FSF-162192]: Runtime problem with NETCDF, Open MPI 1.5

> Dear NetCDF supporters,

Howdy Dr. Markwardt!

Unfortunately I don't have OpenMPI here, I just test on MPICH2.

Can I ask you to try the latest beta release before continuing:
ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-beta.tar.gz

There are some changes to the build process: --with-hdf5= is no longer used. 
Instead set the appropriate CPPFLAGS and LDFLAGS environmental variables. See 
the new build instructions here:
http://www.unidata.ucar.edu/software/netcdf/docs_beta/netcdf-install.html#Quick-Instructions

Thanks,

Ed
