[galaxy-dev] Error in Join two Datasets (version 2.0.2)

Hi, I got an error in “Join two Datasets" (version 2.0.2). /home/galaxy-dist/lib/galaxy/__init__.py:5: UserWarning: Module psyco_full was already imported from /home/galaxy-dist/lib/psyco_full.py, but /usr/lib64/python2.6/site-packages is being added to sys.path __import__( "pkg_resources" ).declare_namespace( __name__ ) Do you know, what could be the reason?
