Sure, that's a problem. When we moved to 5.1 I changed my libraries to
work with both 5.0 and 5.1 and distributed a single package. Since then
I've created packages for 5.1 for almost all my tools. For 5.2 I think
I'll start with the same source but keep separate packages. In any case,
the changes are fairly minor, typically this:

==> 5.1/lrandom.c <==

LUALIB_API int luaopen_random(lua_State *L)
{
 luaL_newmetatable(L,MYTYPE);
 lua_setglobal(L,MYNAME);
 luaL_register(L,MYNAME,R);
 ...
 
==> 5.2/lrandom.c <==

LUALIB_API int luaopen_random(lua_State *L)
{
 luaL_newmetatable(L,MYTYPE);
 luaL_setfuncs(L,R,0);
#ifdef EXPORT_GLOBAL
 lua_pushvalue(L,-1);
 lua_setglobal(L,MYNAME);
#endif
 ...

diff -u 5.1/test.lua 5.2/test.lua
-require"random"
+local random=require"random"
