There's a problem with \realsuperscript in the above code (apart from  
some \makeatletter \makeatother trickery to be fixed): I guess it  
applies to the current SVN version of xltxtra, not the TeXLive-2007  
version.

I must admit I had stopped using XeTeX regularly, and that I just went  
back to it because I'm writing a document for which the Garamond font  
is a requirement. I stopped using XeTeX not because I'm tired of it,  
but because of the many code changes reported here for XeTeX,  
xdvipdfmx and the packages written (like fontspec) or modified (like  
pdfpages) for them: there have been so many changes, I stopped trying  
to keep track of them.

To get up-to-date XeTeX and xdvipdfmx, you need to download source  
tarballs from the SVN repository and compile them. But there are  
problems:

- Compiling xdvipdfmx was kind of a mess on the Mac, last I tried <http://tug.org/pipermail/xetex/2007-April/006316.html 
 >. You need libkpathsea which isn't included in MacTeX, and libpng  
which isn't included in Mac OS X. Hence you need to use i-Installer to  
install gwTeX, which does include libkpathsea, and to install libpng.  
Alas, libpng as installed by i-Installer has static libraries only, no  
dynamic libraries. Taking all that into account, invocation of  
configure should be something like:

$ sh configure
    --with-kpathsea=/usr/local/gwTeX
    --with-ft2lib=/usr/local/lib/libfreetype.a
    --with-ft2include=/usr/local/include/freetype2
    --with-pnglib-libdir=/usr/local/lib
    --with-pnglib-include=/usr/local/include/libpng12
    --bindir=/usr/texbin

But last I tried it failed. Has this issue been solved, and is there  
now a working procedure to build XeTeX and xdvipdfmx from source on  
the Mac? (Apart from using MacPorts or Fink, which I'm not willing to  
try right now.)

- Do the SVN sources include up-to-date versions of all the LaTeX  
packages written or modified for XeTeX and xdvipdfmx? If not, and the  
packages need to be obtained from CTAN, I think I'll pass.

It's these problems which so far made me stick to XeTeX, xdvipdfmx and  
assorted LaTeX packages as shipped with MacTeX/TeXLive-2007. If the  
situation has not changed since last year, I think I'll just go on  
like this, living with the limitations of XeTeX from a year ago (not  
from lack of interest, but from lack of time), and wait for the  
release of TeXLive-2008.
