This is what I found worked for me:

If you want to edit any library you start up a version of XCircuit then 
File/'Read XCircuit File' in the library.lps file.

It ends up in the 'user library'.  Edit it any way that you want, then save 
it out under a new name.  You have a new library that you can read in with 
File/'Load New Library', the next time you start up XCircuit (so that it is 
not in the User section any more).
 
Myself I see adding/changing parts to the libraries that come with XCircuit 
as bad form.  It makes upgrading to future versions harder, and it makes 
version control almost impossible.  So I always copy them off to other 
libraries before I change them.
