No; the problem is that there's a broken link on the Shapely home
page at http://trac.gispython.org/lab/wiki/Shapely - it links to a
non-existent .exe file in this line:
"Windows users should use the executable
installer, which contains the required GEOS DLL"
easy_install is seeing this link and thinks it's preferable, due to
the way it sorts candidate URLs, and it isn't smart enough (yet) to
backtrack on broken links.
You can work around this by adding 'dependency_links=' to your
setup(), replacing the  with a list of specific links to the
individual .exe files; this will keep easy_install from ever reading
the PyPI page or wiki page with the broken link.
Of course, you should also suggest the shapely maintainers fix the
broken link, since it is broken for humans as well as for easy_install. ;-)

<0.6dev will do the trick.
