The idea of having default modules in this variables is this:
Eventually I would like to factor out ome parts of the current org.el
into there own files, in particular much of the link code can move to
such files.  However, I still want Org-mode to be feature-rich out of  
the
box, so I would load those factored-out modules from this variable,
plus offer optional modules for the user to select.

I did not realize that erc is not supported on all Emacs versions,
to we clearly need to cater for this.  Wither by taking it out
of that variable, of my making the require fail silently.
We could, for example, wrap the require into condition-case and only
pus out a message, not raise a signal.
