That is exactly it. You will get the same error if you try COLA's i686 build
which was also uses glibc 2.5. Up to now I had been building the i686
version of the OpenGrADS Bundle on a machine with glibc 2.3.4 as yours.
However, I hit a problem with 2.0.a8 version of gribmap using this version
of glibc. In the end I had to build it on a newer machine with glibc 2.5.

For the record: for binary portability, more important than the particular
version of gcc is the version of glibc. In this particular case, I rebuilt
grads with gcc 4.1.2 and glibc 2.3.4 and I could not get gribmap to work. On
Linux, you can find the glibc version with "ldd --version". In the future
perhaps we should have the glibc version as part of the binary tarball
filename (at least on Linux).

Almost.  I have a build of grads 2.0.a8 on i686 using glibc 2.3.4; it passes
all of my tests (including extensions but not the large grib feature) except
for gribmap. If can make it it available to you offline, but I'd rather not
post it on sf.net because it is not 100% functional. If you do not need the
new large file feature of gribmap you could mix & match and use the
2.0.a7.oga.3 version of gribmap and everything else from 2.0.a8. If
interested,  write to me at dasilva at opengrads.org and I'll make this build
available to you.
