getting an error running a script that

Michael: The NetCDFFile function was deprecated a few releases
back, and recently removed. If you have netcdf4-python installed
you can do
from netCDF4 import Dataset as NetCDFFile
and the script should work as before.
Regarding the second error, you must open the file for write access
(mode='w') if you want to add attributes to the data variables.

Jeff,
No I don't have netCDF4 installed. It's not in the package manager. Wasn't sure
if there would be a conflict with python-netcdf that's installed. Guess that's
the reverse interface. Now I'm having some trouble compiling netcdf4-python
from sources following:
http://code.google.com/p/netcdf4-python/wiki/UbuntuInstall
The configure ended in error:
checking whether the C compiler works... no
configure: error: in `/home/rawlins/Downloads/netcdf-4.2.1.1':
configure: error: C compiler cannot create executables
