Arrrgh! I'm such an idiot! That line ("import hildon") doesn't even need to be there! I will have to fix that for my next release, but if you have a text editor installed, you can get root in a terminal and edit /usr/bin/openhostwin.py and remove that "import hildon" line altogether. It will then work fine. Alternately, you can install python2.5-hildon and it will work. I'm sorry about that stupid bug.
