The new scipy core is completely different from Numeric. It is a
replacement for Numeric.
In the past you had to install
scipy ---| these were sometimes installed together as
scipy_complete or just scipy.
Now, you need to install
You can install both Numeric and newcore if you want (say for
compatibility with old 3rd-party code that has not caught up with the
changes yet). But, old scipy will not work with newcore because they
use the same directory and the __init__ file has changed.
So, just use newcore and newscipy and you will be fine and cutting edge.

You cannot use old scipy (i.e. version 0.3.2) with the new core. You
need to use the new scipy with the new core. Right now, the new scipy
is available by check out from the svn server:
svn co http://svn.scipy.org/svn/scipy/branches/newscipy
svn co http://svn.scipy.org/svn/scipy_core/branches/newcore
gets you the latest scipy_core as well --- the svn repository is usually
in a state where it can compile, since most developers run off of it
