It'll work with all versions of Pd AFAIK.  Pd-extended has the  
advantage of including all the objects, so you don't have to download  
yourself.

Here's a little synopsis of the library issue as I see it:

- First, external objects were provided in multi-object/single-file  
libraries, like many DLL formats.  There were a lot of problems with  
that, mostly revolving around name clashes.

- Next, all objects were built as single files, and put directly in  
"extra", so there each object would be loaded on demand. from a  
single-object/single-file.  This made name clashes much easier to deal  
with.

- In Pd-extended, objects are organized to take advantage of Guenter's  
idea for a namespace in Pd.  This means the single-object/single-files  
are organized into "libdirs" which are basically folders full of  
single-object/single-files that can be loaded as old-style libraries  
(with the libdir patch to Pd-core), or used with a namespace prefix  
(i.e. [iemlib/prepend] or [maxlib/scale].

Hope that clears things up, sorry for the snippy response before.
