i was manually relinking xetex on the platforms i build on, by noticing
the invocation of libtool to link xetex, and changing it to move the
-lfontconfig at the end.

see the patch i posted at
http://tug.org/pipermail/tlbuild/2009q2/000699.html
(and other messages in that thread)

which could allow to solve this in general case, without the need of
manual relinking.

Peter had some objections but i didn't have time to discuss it further.

Best,
