That's the problem. The primitives \XeTeXcharclass and 
\XeTeXinterchartoks were introduced in xetex after the release of 
TeXLive 2007. You thus need version 0.997 (from svn) to use polyglossia 
with French or Turkish ;)  I intend to have a stable release of 
polyglossia in time for TeXLive 2008, and I assume that the final 
release of 0.997 will be part of it, so that should no longer be a 
problem then.

Or perhaps
\setupmainlanguage[<options>]{<lang>}
and
\loadotherlanguages{<lang1>,<lang2>, …} % without options
or
\setupotherlanguage[<options>]{<lang1>} % with options

Currently. if you select the greek language, then \greekfont will be 
selected ONLY if it has been previously defined, otherwise the current 
font is kept with \addfontfeature{Script=Greek,Language=Greek}.

The version of gloss-greek.ldf you tested is not yet optimal. The next 
one will have options to choose between monotonic, polytonic and ancient 
hyphenation patterns, among other things.
