error installing mercurial plugin for eclipse

Question

I am trying to install the picasa web android sample in Eclipse so I am following all the steps, until I get to the step where I have to install the Mercurial plugin for Eclipse.

So in eclipse I try to add the plugin from http://cbes.javaforge.com/update as stated on the hg site but then I get the following error and eclipse cannot complete the install because of the following dependency:

Cannot complete the install because some dependencies are not satisfiable

com.intland.hgbinary.win32.feature.group [1.9.3.v201110131844] cannot be installed in this environment because its filter is not applicable.

How do I fix this?
