It turns out that the patch does not fix my problem. After more =
web-searching, I see I should be using the adopt policy =
(http://www.rasterbar.com/products/luabind/docs.html#adopt), to pass Lua =
object ownership to C++. However, whenever I try to include =
luabind/adopt_policy.hpp, I get tons of errors (on Xcode 4.6.3 with =
clang or gcc).

As you can see, I'm using a version of luabind in the ofxLua project, =
but I also tried taking a copy of luabind directly from Git =
(https://github.com/luabind/luabind), but had a similar pile of compile =
errors. Anyone else run into something similar? More important, can =
anyone help me with this?
Thanks,
Glen.
