It's only a problem when building libraries written in C, since Lua's own
package management is version-aware.  I do this in the Makefile (no C
project is too small for a Makefile).

When making a new Makefile, I copy this stub to the new file before
starting to edit in the new stuff:

-----
# Configuration: LUA must point to your Lua 5.1 or 5.2 include directory
#   and (if 5.1) the corresponding compiler definition should appear in CC

#LUA=/usr/include/lua5.1
#CC=cc -DLUA_5_1

LUA=/usr/local/include/
LIB=/usr/local/lib/lua/5.2
CC=cc

Yes, the Debian underskirt is showing :-)
