This is actually supported as of a few versions ago .. in the default
blue-framed theme, modules for which the underlying software is not installed
appear in the 'Un-used modules' category.

The best way to get this information is by calling the get_visible_modules_categories
function, which returns a list of category hash refs with the keys :

code - A short category code, like 'system' or 'servers'

desc - The human-readable category name

modules - An array ref of modules in the category

unused - Set to 1 for the special un-used category, which contains modules
whose underlying servers are not installed.
