There are two different questions here: what is installed now when  
compiling XeTeX from source (which is what your answer is about I  
think), and what will be installed later when MacTeX-2008 (the Mac  
packaging of TeXLive-2008) is released (which was Paolo's question if  
I'm not mistaken).

In other words, again if I'm not mistaken, Paolo's concern was whether  
installing now XeTeX from source will have any influence on a later  
TeXLive install through MacTeX (whether the files installed now when  
compiling XeTeX from source will take precedence over the files  
installed later through MacTeX-2008). The answer is No.

All this knowing that Paolo uses currently a different TeX  
distribution for the Mac, named gwTeX and installed via an application  
called i-Installer. gwTeX itself is based on a subset (corresponding  
more-or-less to teTeX) of TeXLive-2007.

Actually, there are two different things to consider in a XeTeX  
installation: the binaries, and the accompanying files (LaTeX  
packages, scripts, formats, etc.).

When compiling XeTeX from source, the binaries overwrite those in the  
current TeX installation, while the accompanying files are put in the  
TEXMFLOCAL tree reserved for local additions. When installing later a  
new TeXLive release (MacTeX-2008 for Paolo), precedence will be for  
the new binaries but may be for the old accompanying files.

To be more specific, XeTeX pieces are installed in:

- MacTeX-2007: binaries in /usr/local/texlive/2007/bin, accompanying  
files in (to simplify) /usr/local/texlive/2007/texmf-dist.

- Compilation of XeTeX from source: binaries in /usr/local/texlive/ 
2007/bin, accompanying files in /usr/local/texlive/texmf-local.

- MacTeX-2008: binaries in /usr/local/texlive/2008/bin, accompanying  
files in (to simplify) /usr/local/texlive/2008/texmf-dist.

Precedence will go to /usr/local/texlive/2008/bin for the binaries  
but /usr/local/texlive/texmf-local for the accompanying files. Hence,  
in this configuration it is safer to remove any XeTeX-related pieces  
from /usr/local/texlive/texmf-local before installing MacTeX-2008.

But here the situation is slightly different because Paolo uses  
currently gwTeX instead of MacTeX-2007, yielding:

- gwTeX: binaries in /usr/local/gwTeX/bin, accompanying files in (to  
simplify) /usr/local/gwTeX/texmf.texlive.

- Compilation of XeTeX from source: binaries in /usr/local/gwTeX/bin,  
accompanying files in /usr/local/gwTeX/texmf.local.

- MacTeX-2008: binaries in /usr/local/texlive/2008/bin, accompanying  
files in (to simplify) /usr/local/texlive/2008/texmf-dist.

After using the TeX Distribution pref panel to switch from gwTeX to  
TeXLive-2008, only the binaries and accompanying files from  
MacTeX-2008 will be seen.
