I'm generally very, very bad at keeping those version number indications up-to-date. And since these are libraries I am the developer of, I always use the absolute latest version from Git.

Anyway, the way Hexoshi is distributed is to actually include the needed dependencies, so I'm not too concerned about it. The problem you faced before is, as far as I can tell, because you got a dependency from an unsupported source (pip), so I've rectified that by removing those entirely from PyPI (or whatever it's called now). The only supported way to install SGE or xSGE is through the SGE and xSGE websites:

http://stellarengine.nongnu.org
http://xsge.nongnu.org

The latest released version of both should be sufficient; I don't recall Hexoshi's current Git revision requiring the latest Git revisions of any dependencies.
