Compile error for struct on OS-X

[Dan Christian <danchristian65@...>]

I'm trying to install struct on OS-X (10.11), and am getting compile
errors.  I'm new to Lua, so I might be missing something obvious.  The
details are at the end:

I have Lua51 installed via macports, along with luarocks.  I'll
primarily be using it with luajit.

Anybody have this working?

Is there a way to get luarocks to use gcc?

Where would I send a bug?

Thanks,

Dan
