[XeTeX] xetex.xfmt not found

[Jonathan Kew]

Dear Peter,

Sorry to hear that XeTeX didn't install successfully for you. Gerben's 
suggestion to get the latest i-Installer and re-try the installation 
using that route might solve the problem for you, so that's worth 
considering, I think.

Trying to understand the problem you encountered, the messages you 
quote from the installer log:

>>> Jun  6 12:53:56 : building format files
>>> Jun  6 12:53:58 : fmtutil: no info for format `xetex'.
>>> Jun  6 12:54:00 : fmtutil: no info for format `xelatex'.

indicate that the installation script failed to correctly add entries 
to the fmtutil.cnf file. One possibility is that there are multiple 
such files on your system, and the script located the wrong one; then 
fmtutil isn't actually using the new entries. If you ask the installer 
log to "show everything", there might be some clues as to where it is 
locating files.

If you're comfortable exploring your system from the command line, you 
may be able to locate the fmtutil.cnf file(s) yourself and correct the 
problem. The "postflight" script within the installer package, or the 
"configure" script within the i-Package, contains the commands that are 
supposed to add xetex and xelatex entries to fmtutil.cnf.

Hope this helps,

Jonathan
