I'm quite interested for testing. I have little time right now though,
so can't make any promises - but I'd love to poke when I have a spare
minute.

For building: http://lua-users.org/wiki/BuildingModules

For installing... that's platform specific. Different Linux
distributions are different, and some people like to install into
/usr/local and some people like to install into /opt/. Most binary
modules for Lua expect you to edit the paths in a config or makefile
before you run make. I suggest you take a look at a makefile of an
existing module with the same licence and borrow from that. I think
installing the .so to '/usr/local/lib/lua/5.1/tuna.so' by default
would be sensible (it may need to create the directory).

Also sensible would be to make a rockspec for luarocks. Well worth the
time (which, depending on the complexity of building the module, isn't
usually very long). See the 'Tutorials' section here for examples:
