Sounds like a bug, except that 1.0.10 > 1.0.9:

 >>> from pkg_resources import parse_version as pv
 >>> pv('1.0.9')<pv('1.0.10')
True
 >>> pv('1.0.10')>pv('1.0.9')
True

So it's not in the version testing, or shouldn't be.

Try using the -v option to easy_install and see what URLs it's 
picking up.  Also, is the problem reproducible?  i.e., if you get rid 
of the new version and put back the old, do you still have the same problem?
