That's why the TeX Live configure script doesn't offer a --with- 
system-icu option; you'd have to work extra hard to mess it up in  
that way! No, I was mostly wondering about the FreeType versions, but  
you seem to have the same as I do.

Hard to be sure from this output, but you can easily determine which  
is failing by running "xelatex -no-pdf" followed by "xdvipdfmx -E"

It could easily be the same underlying bug on both systems, just  
manifesting differently because of the different architectures.

I think I can have access to an OpenBSD machine (i386) at the office  
in a couple of days, so will try to investigate there, if I can't  
reproduce/solve the failure before then.
