Numeric is an old, obsolete package. numpy is the successor. You
installed numpy, not Numeric. Unfortunately, there is no Python 2.5
binary available for Numeric. I am not familiar with the Reed Solomon
coding package that you are using, so I don't know if there is an
updated version that uses numpy instead of Numeric. If it is open
source, and you can show us the source, we can help you convert it to
use numpy.
