Problems running Phyton scripts

When I just load blender, the console says:

E:\Programas\Blender\Phytons\os.py:282: Warning: ‘yeld’ will become a reserved keyword in the future
’ import site failed '; use -v for traceback
Using a clean Global Dictionary.
File "<string>2, line 282
yeld top, dirs, nondirs

I searched on os.py but don’t really know what to do there.

Now some more general questions:

Phyton files are on "E:\Programas\Blender\Phytons and blender .py files are on “E:\Programas\Blender\Phytons\Blender” I configured the file path on Blender to be “E:\Programas\Blender\Phytons” which contains ALL of them is that the correct way?

Where do I have to install “Dynamica” and how do I call it from Blender?

Thanks in advance.

You may already have seen this. If not:

What OS?
What distro/flavour?
What version of Blender?
" " " Python?

Dynamica should be in the same file as blender. Any script that needs it will call it from there.

Use python 2.2 instead of 2.3.

Thanks a lot!!
