...some random notes. (such a long email trail here, I'll put
everything up top)
I don't know about rpy2 from easy_install. Last fall I installed it
from a source download. let's see...
unzip the source, then in the source folder:
python setup.py build
sudo python setup.py install
About trying to execute the GDAL binary - it's a library.
For the numpy requirement, the system Python includes an old 1.0
version, but my GDAL framework includes a recent 1.1 version. I'm not
sure if the numpy version is important.
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):

If I do:
import rpy2.rinterface
in the Qgis python console, I get the IOError. If I do that in a
Terminal python session, no error.

Subject: Re: Hello,
Sebastian,
I'm really not much better (any?) at figuring this stuff out than
you. I don't know why python would not be detected. Can you run
python from the terminal? If so, try a command like 'import rpy2'
and see what happens. Same with other modules you need.
Frankly, the homerange plugin never quite worked for me on OS X. I
think it did for a while, then did not. I'm not sure why, and I gave
up. You may also look at the manageR plugin, but you will have to
learn R commands for doing your analyses. R is a great program, and
you can get the binary online. In fact, you should already have it
to get rpy2 working (I think). Don't forget, rgdal is available from
William's site as a binary. I assume you tried that.
I would encourage you to contact the dev of the plugin if none of
the above helps. They are better at reading those outputs than I am.
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

Hi John,
I have to say I am not surprised by your reaction to the email I
sent you, I also cannot make any sense out of it (and I know very
little compared to you). I was wondering if the following messages
makes more sense to you:

This is a message I get when I start up QGIS. The problem seems
to be GDAL mostly, which relates to the message I sent you
earlier. But overall I think the problem radicates in Python. 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?
I am sorry to keep bothering you with questions, but I really want
this work.

Hi John,
Thank you for the lenthgy email you sent me. You are correct,
I have not set up the environment. I followed your
recomendations but encountered yet another problem. When
trying to communicate with GDAL, I get the following message:
/Library/Frameworks/GDAL.framework/Versions/1.6/GDAL ; exit;
sebastian-cruzs-macbook:~ sebastiancruz
$ /Library/Frameworks/GDAL.framework/Versions/1.6/GDAL ; exit;
-bash: /Library/Frameworks/GDAL.framework/Versions/1.6/GDAL:

[Process completed]
I do not know why the binary is having this problem. I had the
same issue instally rpy2 from terminal, with install sudo
easy_install -U rpy2.
(zip_safe flag not set; analyzing archive contents...
No eggs found
in /tmp/easy_install-fULGJF/rpy2-2.0.6/egg-dist-tmp-Ddqx_x
(setup script problem?)
My python is 2.5, that came witht he MacoSX operating system.
I have not installed any other version.
Something is wrong with my system it appears.
Sebastian
