[Qgis-developer] SAGA modules (version 2.1.0) through SEXTANTE on Mac OSX

[Olav Peeters]

A quick and dirty circumvention of the check is to change line 373 in 
~/.qgis/python/plugins/sextante/saga/SagaAlgorithm.py
to:
if "" in line:
(restart Qgis)

this way the modules do open since the check is basically disabled.
The original code should also though. Maybe it's encoding related.
When I execute a Saga module, this happens during saving the output:

An error has occured while executing Python code:

Traceback (most recent call last):
   File 
"/Users/myaccount/.qgis//python/plugins/sextante/gui/OutputSelectionPanel.py", 
line 95, in saveToFile
     self.text.setText(str(filename))
UnicodeEncodeError: 'ascii' codec can't encode character u'\xff' in 
position 2: ordinal not in range(128)

Should I have compiled with a different locale set?

We are nearly there :-)
