I guess there may not be an option to link statically with the C and C 
++ runtime libs; this isn't supported (in TL at least) for all  
platforms. Pity, though, as that may be a source of incompatibilities.

I think this must mean that the NetBSD linker is following  
fontconfig's dependencies, as xdvipdfmx does not have a *direct*  
dependency on libexpat or libz. It does use freetype but should be  
linking with the static freetype in TL, but your libfontconfig  
probably uses freetype as well.

Could you show us the link command from the build log, to see how the  
libraries are actually being specified there?

I think libpthread is being pulled in by ICU. But it shouldn't be  
needed, as xetex isn't multi-threaded. Maybe we could run ICU  
configure with the option "--disable-threads"; that would probably be  
a good idea. I'll try to look into that a bit more. Aside from that,  
I guess xetex will have the same issues as xdvipdfmx with pulling in  
dependencies of fontconfig.
