Maybe there was an automatic update? Otherwise it's rather strange.

If you want to build from source, you may try the tarball I did on
http://www.environnement.ens.fr/perso/dumas/fc-srpms/grads-1.9b4.tar.gz

FC-3 has all the required rpms, except libgadods. (you may need hdf-devel
udunits-devel netcdf-devel readline-devel libdap-devel libnc-dap-devel
libsx-devel Xaw3d-devel zlib-devel libjpeg-devel gd-devel ncurses-devel
libpng-devel). But you won't have libgadods, the version currently available
doesn't build with recent libdap. It seems to me that it is worked on.

In the end there also may be issues with other symbols, but this one
make me guess that there is an incompatibility between the libstdc++
version that was used to build libgadods and the FC-3 libstdc++. If you
a old static library of libstdc++, maybe you could recompile, but I'm not
sure. And there is still the library binary interface incompatibility issues
that will remain even after the recompilation from source, for libdap++.a
from supplibs (maybe not for FC-3, but it seems so from your report above).
