Finally it turns out some pieces inside texmf.local are more recent  
than those from texmf.texlive (like Will Robertson's fontspec,  
ifxetex and xltxtra), while others look older (like hyphenation files  
and xetex.pool).

I guess I see this because I must have installed XeTeX from source  
using the SVN tarball, which includes more recent versions of some  
elements than in TeXLive.

I feel a bit unsure about what should be done, and about the  
compatibility between XeTeX as an add-on (as it was with teTeX) and  
built-in XeTeX (as it is in TeXLive). For example, do the hyphenation  
files in /usr/local/TeXLive/texmf.texlive/tex/generic/xu-hyphen/  
fully replace those in /usr/local/TeXLive/texmf.local/tex/generic/ 
hyphen/? Will the presence of the latter perturb the operation of  
XeTeX when installed with TeXLive?

Fortunately I don't need XeTeX this week, so that this will wait.
