[XeTeX] polyglossia and ledpar conflict

[Daron Wilson]

Hello,

I'm using the XeLaTeX on Mac OS X 10.6, with MacTeX 2009 installed. According to the TeXLive Utility that comes with MacTeX 2009, all the packages installed are up to date

I've been working on typesetting a document with parallel texts, having English on the left and Greek on the right.    I started with the LateX packages ledmac and ledpar because I would like to keep the English and Greek synchronized, and I've managed to get a reasonably long source document to compile satisfactorily, apart from a couple of protruding lines due to lack of hyphenation support.  I'm fairly new to LaTeX, but after poking around a bit, it seemed like the polyglossia package would help here.  On adding polyglossia, the document would no longer compile, though I've managed to narrow the problem down to an apparent conflict between polyglossia and ledpar.

I've included a small document below that illustrates the problem.  When I try to compile as written, I get the error message shown at the bottom here. When I comment out the ledpar package, everything compiles perfectly. In my editor, the line number listed for the error is always the line containing the actual Greek. (line 15 here)

I'm not sure if more information is needed, but if anyone could point me in the right direction for a solution, or let me know if this a "time to move on" problem, I would be grateful.  If there would be better/easier ways to get good Greek hyphenation with XeTeX that would be helpful also.
