buildout and setuptools requirement

buildout and setuptools requirement

when I call python ./bootstrap.py on mutual server I have this error
Traceback (most recent call last): File "./bootstrap.py", line 74, in
ws.require('zc.buildout') File
"/usr/local/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg/pkg_resources.py",
line 666, in require
File
"/usr/local/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg/pkg_resources.py",
line 569, in resolve plugin_projects = list(plugin_env)
pkg_resources.VersionConflict: (setuptools 0.6c11
(/usr/local/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg),
Requirement.parse('setuptools>=0.7')) when I do the same on my computer,
it is working fine.
before this I did :
easy_install --install-dir ~/download fez.djangoskel paster create -t
django_buildout xxxxxxxx
does anyone know what could be the problem ?
thanks
