The only difference between the "R-base" and "R-base-with-hdf5" RPMs is
that the latter can read and write files in HDF5 format (This capability
is determined at compile time, which is why we need to distribute two
binary versions).  If you don't need to read and write HDF5 files, just
use the "R-base" RPM.
