The "scripts" feature installs scripts with no write 
permission. This is a good thing. But when copying 
scripts down into build/scripts or installing into the 
target python, there are failures because distutils 
does not have write permission on the target when it 
has been previously installed. I assume attempts to 
uninstall are going to have similar difficulties.

In a related matter, we have had to create 
an "artificial user", which is a big pain, who owns 
the files installed because Distutils doesn't work 
right when the file has group write but is owned by 
another developer.
