          1. ROC France: With our UIs we got some problems with Python for several VOs because those VOs use their own Python version (> 2.3.x). Unfortunately, UI installation provides standard python2.3 libraries within the externals directory, and set the PYTHONPATH accordingly. By the way, to be able to use their own python installation, VOs must convenably update the PYTHONPATH variable to ensure that the right version of the required libraries are firstly taken into account. Make sure also that you call the right python binary.
