[XeTeX] Running xelatex on the examples in XeTeX_doc.zip

[Ravi Parimi]

Has anyone been able to generate pdfs out of the sample docs extracted
from XeTeX_doc.zip
(http://scripts.sil.org/cms/scripts/render_download.php?site_id=nrsi&format=file&media_id=xetex_doc_094&filename=XeTeX_doc.zip)
?

I cannot get any of them to work on my Max OSX running 10.5.8 with a
TexLive 2008 install. For e.g:

$xelatex Hindi.tex
This is XeTeXk, Version 3.1415926-2.2-0.999.6 (Web2C 7.5.7)
