Copy & Pasting the exact error message helps tremendously.

Are you sure you have them installed successfully? How did you install 
them? (Precompiled or from source, and if so, with which compiler?) 
IIRC, Scientific doesn't come with the NetCDF, you have to install the 
NetCDF library separately.
(See http://www.unidata.ucar.edu/software/netcdf/ for download.) After 
installing the NetCDF library, you might need to reinstall Scientific to 
  get it to recognize the NetCDF install.

You might also want to check out 
http://dirac.cnrs-orleans.fr/mmtk_wiki/WindowsInstallation - strictly 
speaking, it's installation instructions for MMTK, but you can ignore 
the final steps of installing MMTK, if you want.

If you need further help, you can always try a more specific resource, 
like the MMTK mailing list - 
http://starship.python.net/mailman/listinfo/mmtk (MMTK is written by the 
same person (Konrad Hinsen) as Scientific, and depends on Scientific.)
