PyPI uploads aren't a suitable basis for analyzing "dev" use cases, 
since the whole point of having a "dev" tag is for *non-released* 
versions.  (E.g., in-progress development via SVN.)  Dev tags are so 
that while you're doing development, your locally-installed versions 
can be distinguished from one another.
