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:
############################################################################################

 And I really have no idea what's wrong with galaxy and python.
Thanks for your help and advice.
