0.2.2.dev-r21160 was installed, but your requirement was for 0.2.2-r21160.

The installed version is r21160 of an in-development pre-release of 0.2.2, 
while your requirement is for an r21160 *post*-release patch of 0.2.2.

In other words, the error is due to a typo in your requirement.

With respect to the idea of doing SVN updates of dependencies (as opposed 
to doing fresh checkouts and egg builds), it's an interesting idea but it 
seems like the implementation would be complex, to say the least.  A key 
issue is that .egg-link files don't have any way to point to their 
project's setup script.  But I'll give it some thought for when I start 
work on 0.7, which will be refactoring some internals of the 
requirement/resolution system anyway.  Maybe there will be a way to work 
something in then.
