Ok, but if TeXLive manages to compile some .so files (for XeTeX for instance IIRC) and make it generic enough to be used under Debian, Suse, etc. then I fail to see why it wouldn't manage to compile some .so files for LuaTeX the same way?
(1) TeXLive does not compile any .so files for XeTeX but rather uses the libfontconfig.so.1 of the system installed in, e.g., /usr/lib64/. (2) The trick is to compile the x86_64-linux binaries on a system with a fairly old version of the GNU C Library in order not to depend on symbols introduced more recently and not available on, e.g., CentOs5. Compiling an .so on such a system would help but there is still the problem of different versions of other shared libaries. Regards Peter
