I just released my first new piece of software using Distribute, and  
I'm still confused about whether I have the packaging correct.  I  
think not, because a user has reported receiving a SandboxViolation  
error when trying to install the package with easy_install (bug report  
at: http://bitbucket.org/dhellmann/ical2org/issue/1/unable-to-install-ical2org-with) 
.  The relevant portion of the error message seems to be:

That looks like the script is trying to install Distribute itself,  
based I suppose on having it in the install_requires list in my  
setup.py.  I added distribute to install_requires after on an apparent  
misreading of the instructions on http://pypi.python.org/pypi/ 
distribute.

So, my questions:

1. While researching the problem this morning, I came across the  
instructions at http://packages.python.org/distribute/setuptools.html#using-setuptools-without-bundling-it \
 , which seem like a much more sensible way to bootstrap the  
installation of Distribute than install_requires.  Should I have used  
that instead of install_requires?

2. If I don't require Distribute for installation, will my package  
work with the older setuptools (assuming I'm not using any Distribute- 
specific features, which I don't think I am, but I'm not sure I know  
what those are).  In a nutshell, do I need to force my user to install  
Distribute at all before using my package?  And if so, what is the  
preferred way of doing that?

Thanks,
Doug
