Hello, galaxy developers and maintainers: I'm a user from the Chinese mainland. I have ubuntu 12.04 OS and python2.7.3 interpreter. After confirming that I've installed openssl-dev and bzip-dev and python version >2.5, I use virtualenv to create galaxy_env and just run "hg clone https:xxxxxxxx/galaxy-dist; cd galaxy-dist; sh run.sh" in the directory of galaxy. It seems that it's not the problem of linux w/r/x permission. After downloading some egg of python, the shell display as follows: ############################################################################################ /home/don/galaxy-dist/lib/galaxy/__init__.py:79: UserWarning: Module markupsafe was already imported from /usr/lib/python2.7/dist-packages/markupsafe/__init__.pyc, but /home/don/galaxy-dist/eggs/MarkupSafe-0.12-py2.7-linux-x86_64-ucs4.egg is being added to sys.path self.check_version_conflict() .................. ..................
