Hello Walter,

     I can't thank you enough for your help.  Yes, I usually use the 
Synaptic Package Manager, however in this case, Python version 3.2 is 
not on the Synaptic package Manager.  This is why I chose to build it 
from source.  As far as what I think is causing this when I go in the 
Terminal and type:
p me out.
sudo update-alternatives --install /usr/bin/python/python3.2 python 
/opt/py32/bin/python3.2 1

I get this as an error message:

update-alternatives: renaming python link from /usr/bin/python to 
/usr/bin/python/python3.2.
update-alternatives: warning: forcing reinstallation of alternative 
/opt/py32/bin because link group python is broken.
update-alternatives: error: unable to make 
/usr/bin/python/python3.2.dpkg-tmp a symlink to 
/etc/alternatives/python: No such file or directory

I must add that I am running this in the Terminal under the Python-3.2 
directory that I uncompressed after I downloaded it.  The reason why I'm 
using this version of Python is because Blender2.5, a 3D animation open 
source program is built on Python3.2 and requires it if I am to develop 
it using CMAKE.  And, so far, I have blender installed on /opt/py32.

     I really appreciate your help, and am learning tons by going 
through this.  I understand that posting this question here may not be 
suitable, but I'm confident someone will be able to help me out.
Thanks so much.

Best Regards,

Nevins Duret
