make docs in Vagrant fails

[tomgross]

The command make docs in a current checkout 1623c30fd4f5694f2873c4bd7d6b18bca5a90b91 fails with

vagrant@mockup:~$ cd /vagrant/
vagrant@mockup:/vagrant$ make docs
rm -Rf mockup/docs; mkdir mockup/docs; cp -R .git mockup/docs; cd mockup/docs; git checkout gh-pages;
Checking out files: 100% (5004/5004), done.
Branch gh-pages set up to track remote branch gh-pages from origin.
Switched to a new branch 'gh-pages'
# if test ! -d mockup/docs; then git clone git://github.com/plone/mockup.git -b gh-pages mockup/docs; fi
rm -rf mockup/docs/dev

It seems like a problem with missing dependencies: http://stackoverflow.com/questions/15444020/cannot-find-module-findup-sync-when-trying-to-run-grunt

resolve findup-sync coffee-script ...

[vangheem]

If you add those missing dependencies, it works?

It goes further but I stoped trying at some point.
