Hi Sebastian, 

first I apologise for lack of testing on Mac.
This error log is not telling so much about the source of the error...

Anyway, check if you have installed the correct version of the plugin:
for QGIS <1.0, use HomerangePlugin v1.x, for QGIS >=1.0, v2.x. Using
Faunalia 3rd party repository, the correct version only will be
available via Fetch Python Plugins.
I suggest also to check all dependencies and compatibility. On the wiki
page [0] there is a list of tested configurations. 
As a final check, following John's suggestion, try importing manually
the modules in QGIS Python shell. 

<code>
import rpy2.robjects as robjects
import rpy2.rpy_classic as rpy
</code>

and report on Animove Trac [1] any further problem.

The dependency check is left to the user at the moment - if anyone has
some idea about how to automate it, they are most welcome.
I can also tell you that manageR has very similar dependencies, so
making it work will also affect HR plugin.

BTW, if anyone has a running configuration for HomeRange plugin on Mac,
it would be nice to report all useful details and add them into the wiki
page :)

hope this helps and best regards,
Anne

In terminal I can prompt Python 2.5 and make simple tests (2+2=4) witthout a problem. But for example when trying to install Numpy from a binary, it says it cannot detect python 2.5 in my system. Do you think an upgrade would work?
