EMEN2 Dependencies

EMEN2 is dependent on several other packages. With the exception of Python, which is generally up to date and well-packaged on most systems, I recommend downloading the latest version from the project's site and installing it, or using easy_install for the package if possible. (Linux/Mac package management systems often have out of date software.)

If I have specified a version, it is the minimum version I have tested EMEN2 with. I cannot guarantee success with versions earlier than noted.
