Cannot install working demos

[gtoffoli]

I plan to integrate the OERPUB version of the Aloah Editor with an EDMS and to experiment it in the editing/remixing of OERs.
Following the instructions "Get a dev environment for Aloah setup", I got a site running at http://oerpub.commonspaces.eu/Aloha-Editor/.
The demo page seems identical to the one at http://oerpub.github.io/Aloha-Editor/, but the 2 demos "Connexions Editor Demo" and "OERPUB Editor Demo" lacked interaction and showed different styles.
I realized that bootstrap wasn't found since the bower_components sub-directory was missing; then installed bower and run the "bower install" command. Even if I am just beginning to know what bower is, it seems to me that it did what it was expected to do. But in the 2 demos the interaction still isn't working; the browser console log says "Bootstrap's JavaScript requires jQuery version 1.9.1 or higher", since the version of jquery required by bootstrap is not used.
I noticed also that

• the demos at http://oerpub.github.io/Aloha-Editor/ use an old version of jquery too, but they don't produce the error message above
• in both installations, in the HTML source of the "OERPUB Editor Demo" the attributes of the TAL templating language aren't intepreted
• in both installations, in the "Connexions Editor Demo" the rendering of the math formulas disappear, while with a more recent version of jquery it persists.
  Could somebody update the installation doc and the demos in the oerpub Git repository and give me some suggestions on how to proceed? Should I get the software from the Git repository of the Connexions project?
  Thanks a lot in advance.
