You will need "numpy" rather than "Numarray", its a little confusing 
because both packages are from the same team:


But this shouldn't make any difference to the NetCDF problem.

Have you tried putting it in C:\Windows\System32\netcdf.dll instead/as well?

That's not good is it?  I can't think of anything else to suggest right now.

I'll try and (re)install MMTK on a Windows XP machine using the 
downloads to double check the instructions work with the updated 
packages this afternoon.

(I've been struggling with NetCDF on Linux the last few days - will make 
a nice change)

I know MMTK and Scientific will compile with MS Visual C++ 6.0 (aka 
Visual Studio '98), but haven't tried with the new version Robin 
suggested (MS Visual C++ 2003 command line compiler).
