Hi Ken,

this is a bit of a problem. Since on non-mac systems xetex uses the system fonconfig
library and everything that comes with it (on my linux system that's
libfreetype, libexpat, and libz), it is probably best to use system versions
for all of them (specifically libfreetype and libz) -- for xetex only.

I'll think about a way to do that. That should be easy provided there is a
libfontconfig.la that automatically pulls in all libraries required for
fontconfig.

You could test this by removing
 	xetex_ldadd += $(FREETYPE2_LIBS) $(ZLIB_LIBS)
 	xetex_dependencies += $(FREETYPE2_DEPEND) $(ZLIB_DEPEND)
from texk/web2c/xetextdir/am/xetex.am and then run automake in texk/web2c/
(or remove the corresponding pieces from the resulting
texk/web2c/Makefile.in).

I think you have to keep
 	xetex_cppflags += $(FREETYPE2_INCLUDES) $(ZLIB_INCLUDES)
and pray that the installed headers and those from the TL tree are
compatible.  Not very nice, but might work.

I'd love to check that the installed freetype headers come from the same
version as those in the TL tree, i.e., currently 2.3.9 but at the moment
don't see how to do that (other that compiling a small test program checking
just this).

Peter
