[Matrix-SIG] Q: scientific netcdf crashes python on import?

Can you import Numerical Python correctly? Just start Python and type
"import Numeric". If that doesn't work, importing netCDF won't work
either, because it does the equivalent of "import Numeric" internally.
That (i.e. a missing or faulty NumPy installation) is the most
frequent cause for this error message in my experience. Also check if
your netCDF library is working (e.g. by running the ncdump utility).

Which RPMs are you using? My laptop is a RedHat 6.0 system as well,
and it runs everything fine, using the RedHat Python RPMs, the NumPy
RPMs from Oliver Andrich's collection, and the ScientificPython RPMs
from my Web site.
