In addition to the last error, when I quit and restart qgis after loading and installing the HomeRange plugin, I get this error during startup. Afterwards, the HomeRange plugin cannot be loaded:

Couldn't load plugin "HomeRange_plugin" from
[snip]
Traceback (most recent call last):
[snip]
File "/Library/Python/2.5/site-packages/rpy2/rinterface/__init__.py", line 6, in
    R_HOME = os.popen("R RHOME").readlines()
IOError: [Errno 4] Interrupted system call

The same error is given by manageR [0], therefore I guess it is a rpy2 issue. You can try the function that returns this error alone in a Python shell. On my WinXp machine it returns the correct path to R installation. If it succeeds, try in the Python shell each function of the traceback stepping backwards.
Consider also filling a ticket on RPy2 bugtracker on SourceForge [1].

thank you for testing and best regards,

Anne
