Set OTB environment variables in OSGeoLive image

[loicd]

The OTB python API currently does not work "out of the box".

PYTHONPATH=/usr/lib/otb/python and ITK_AUTOLOAD_PATH=/usr/lib/otb/applications have to be set by the user. Could that be done directly when building the image?

path now available, but permissions needed to create dot-pyc (?)

This is in the /usr/lib/otb area .. what is the right fix ?

user@osgeolive:~$ python -v
...
>>> 
>>> import otbApplication
import otbApplication # from /usr/lib/otb/python/otbApplication.py
# can't create /usr/lib/otb/python/otbApplication.pyc
