I've never used luabinaries, but a couple observations:

- the last luasocket release doesn't support lua5.2, so you aren't
using a standard release, what version of luasocket are you using?
where did you get it?

- I just checked, and the luasocket v2.0.2 (last official release)
"make install" does in fact copy the files. I suspect you are doing
"make", but not "make install". If this is not the case, provide the
make output.

liblua.a is a static library, it will never be found by a dynamic
linker. liblua.a should be statically linked into /usr/bin/lua, and
it's symbols available to any .so loaded by lua. But it isn't, which
might have something to do with luabinaries.

Something is deeply hosed with your system, lua5.2 should look like:

% lua5.2
