dub compilation for osx and lua 5.1

[yannick]

os x homebrew has a package lua51
when i install this and try to compile a sample program it fails since the lua library is
/usr/local/lib/liblua5.1.dylib

however when i do

dmd -w -wi -ignore -m64 -I../luad/ -L-L../luad/lib -L-lluad -L-llua5.1 -debug -gc -ofx source/app.d

where ../luad/ is a checked out version of luad it works.
i'm not completely sure how/where this needs to be fixed

"libs-posix": ["dl", "lua5.1"]

did the trick

[JakobOvrum]

The repository includes custom-compiled Lua binaries for Linux and Windows platforms because of #35, so adding the default system library to all POSIX configurations is not an option. Do you know if D exceptions work with typical Lua libraries built for OSX?

@JakobOvrum not sure what you mean by that, but when you throw an exception within d code that is called from within a lua state then its not caught by lua state and the program crashes as follows:

luad.error.LuaErrorException@luad/state.d(55): [string "..."]:4: object.Exception@source/app.d(10): what is love
