No, the problem is a missing shebang, causing the python script to be
interpreted as a shell script. A proper `easy_install` begins with:

     #!/usr/bin/python
     # EASY-INSTALL-ENTRY-SCRIPT: [...]
     __requires__ = 'distribute==0.6.10'
     import sys
     from pkg_resources import load_entry_point

The bit about an X server comes from `import`, which is a screen
capture tool from ImageMagick.
