My memory's a bit hazy, but IIRC, these symbols are no longer defined
in newer versions of glibc, having been replaced by locale-aware
versions (see, eg,
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=86465).  Perhaps
the netcdf library being linked against
(/home/walkup/local/netcdf-3.5.1/lib/libnetcdf.a) was created with an
older glibc?  In that case, perhaps linking against a netcdf library
which was created under the current glibc would work?  Don't know if
such a library exists offhand.
