Can anybody help me? thanks in advance :)
Answer
You will need to set LUAINC.
Since you didn't specify which OS you are using, I can't give you a
definitive answer what to set it to. On Debian, if you want to build
for Lua5.1, set it to -I/usr/include/lua5.1/
You can set the variable by editing config (which is included from
makefile) or by specifying it on the command line:
$ make LUAINC=-I/usr/include/lua5.1/
