Hi all,
With all this, I was able to install and enable the HomeRange plugin
in Qgis 1.1.0 once - it loaded and showed up in the plugins menu.
After restarting Qgis, I got an error loading HomeRange:
Traceback (most recent call last):

This appears to be a general PyQt problem with 'popen', and appears to
be especially problematic for macs. I think what's happening is that
PyQt is interrupting the (slower?) os.popen command, making it
impossible for rpy2 to find RHOME. This is why things work when entered
into a normal console...
I have yet to find a way to effectively fix it, but I'm going to look
into it further tonight, so hopefully I'll have a solution in the next
few days. It actually doesn't happen all the time, which makes it
slightly harder to pin down. ...
