On my Ubuntu system (12.04), after installing python-scientific,
Scientific.IO.NetCDF.NetCDFFile could be imported without any problems (and
the likelihood that 11.10 is broken in this regard is very low). My guess
is one of two things happened: you have another (non-system) python (type
'which python' to make sure that it returns /usr/bin/python) that is being
invoked by default -- this 'other' python would not have the Scientific
package. Or, python-scientific did not install properly. Note the
difference between scipy and ScientificPython -- they are distinct packages
that do different things.
Good luck,
Jason
