Greetings,
I've successfully used the source version for the past 4 or 5 versions using: "sudo python setup.py develop".
However, 8.0.26 gives me the following error:

*
* Running resources
*

Creating scripts.pickle
Creating builtin_recipes.xml
Traceback (most recent call last):

key=lambda key: getattr(mapping_of_recipe_classes[key], 'title',
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 1: ordinal not in range(128)

any suggestions?
btw, I don't want to use the tar.bz2.
