I am trying to install pyuml in eclipse 3.5.1 with pydev 1.4.6.2788 with the update site but I am getting the following error:

Cannot complete the install because one or more required items could not be found.
  Software being installed: PyUML Feature 1.2.0 (pyUML.feature.group 1.2.0)
  Missing requirement: PyUML 1.2.0 (pyUml 1.2.0) requires 'bundle org.python.pydev [1.4.3,1.4.6)' but it could not be found
  Cannot satisfy dependency:
    From: PyUML Feature 1.2.0 (pyUML.feature.group 1.2.0)
    To: pyUml

anyone knows how to install it?

thanks for your time
