You'll need to reference the network support library for the XDR
routines.  Add `-lnsl' to the above build-line, e.g.

    f77 -o rdtest.ex rdtest.F \
        -L/wrk/d0/newsoft/netcdf/netcdf-2.4-beta5/lib -lnetcdf \
        -lnsl

Please let me know if this works.

The above are just error messages from the configure script as it tries
to figure out your system.  They may safely be ingored.
