1) Check that your netCDF installation includes a shared library  
version. On some machines and with some netCDF versions, shared  
libraries must be requested explicitly during netCDF installation using

	./configure --enable-shared

2) Make sure that ScientificPython is installed after netCDF and  
finds the correct netCDF installation (there might be several on your  
system). The ScientificPython installation script prints the path to  
the library it uses, so it is easy to verify.

This crash is in fact not related to netCDF, but to Numerical Python.  
With Python 2.5, you should use Numeric 23.8.2, available from the  
ScientificPython Web site. With older Numeric releases, you can get  
error messages or crashes at the termination of a Python script -  
this is not really serious as nothing is lost, but it does look ugly.
