Trying to import to blender from makehuman?

I am trying to import a makehuman model (I have the latest nightly build) to blender (2.58a). when I was finally able to change my user settings without it crashing, I clicked import, found my file, and tried to import it. I got an error that says I need the latest nightly build (which I *just* downloaded). any idea on what I may be doing wrong, or how I can fix it?
