Have you considered  using a Bnode to denote the  installation on  a 
person's computer ?  
In  N3 it would look something like:

[ foo:installDirectory  <file:///C:/wherefor/whatever/> ;
  foo:installedName "Seth Russell";
 ..... other parameters relative to the clients installation ...]

With the new RDF syntax you could use a Bnode ID to refer to it from 
other nodes.

Essentially they would still be relative paths - but relative to the "installation path" of the application my package is an extension for. The actual installation path will be different for different users; still that installation path will also be the target installation path for my package, so (more or less): a path relative to the distribution == a path relative to the installed package AND a path relative to the installed package == a path relative to the user's application path.
