Unfortunately, ocsigenserver did not install out of the box (does the following apt output sound familiar?):

dicosmo@ocsigen-vm:~$ sudo apt-get -t experimental install ocsigenserver

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:

But thanks to many wonderful people (see my previous post on this subject), the only thing I had to do was:
