It does "try" it - and the URL looks like a web page URL, so it treats it 
as a web page.  Something like half of the Cheeseshop packages that have 
download URLs, point to web pages.  And those that don't point to web 
pages, are URLs that end with a distutils filename like 
"foobar-1.9.tar.gz".  EasyInstall doesn't download the ones that look like 
files; it downloads the ones that look like webpages, in order to look for 
links.

All of this behavior is documented quite extensively in both the setuptools 
manual and the easy_install manual, including how to use the #egg notation 
to override easy_install's interpretation of links.
