Hi, 
I need to install version 4.0.0 of the Cactus but when I type the command GetComponents --parallel https://bitbucket.org/einsteintoolkit/manifest/raw/ET_2011_10/einsteintoolkit.th asks me to "please enter the path to hg:" and not what is the path...

Dear Camilo,

It wants you to have Mercurial installed.  You would need to install Mercurial.

That is an ancient version of the toolkit; is there a reason that you are not using the latest released version, from http://einsteintoolkit.org/download.html ?  We don't have the resources to support old versions of the toolkit - we can only really support the current release.  The latest release no longer requires Mercurial.
