No, that line would be fine. The bug is version mismatch somewhere in  
the macro files: you must have an etex.src that is version 2.2, but  
language.def is older.

In the TeX Live repository, I only see etex.src version 2.1, so I'm  
wondering if Gerben has included a newer version, but failed to  
update all the associated files. But that's only a guess. The formats  
build correctly with a current checkout of the TL files, but that's  
in a state of flux, and I don't know how it compares to the various  
versions of GW's packages.

When using a current TeXLive package (based on the not-yet-finished  
TL2006), you should NOT attempt to install any additional XeTeX  
package, as xetex is already present in TL.

Current binaries (etex, pdfetex, xetex) support the flag -etex as an  
alternative to the "*", so that is not the problem. The xetex package  
hasn't been updated lately, and currently the code in the TeX Live  
repository is the very latest that's available. (Once TL2006 is  
stable and released, I'll review the separate xetex packages as well.)
