DmxSimple Library Issues on MacBook

I download the DmxSimple library and copy it where expected:
/Documents/Arduino/libraries/DmxSimple

I load my sketch and by the colored highlighting of the DmxSimple commands, the editor seems to have recognized the library.
When I verify though, I get a long list of errors...

/Documents/Arduino/libraries/DmxSimple/DmxSimple.cpp:11:20: error: wiring.h: No such file or directory
/Documents/Arduino/libraries/DmxSimple/DmxSimple.cpp: In function 'void dmxBegin()':
/Documents/Arduino/libraries/DmxSimple/DmxSimple.cpp:57: error: 'digitalPinToPort' was not declared in this scope
/Documents/Arduino/libraries/DmxSimple/DmxSimple.cpp:57: error: 'portOutputRegister' was not declared in this scope
:

Although DmxSimple.cpp is in the library, it seems not to be able to find other components.
Have I installed the library in the wrong place?

no its an old library and when 1.0 came out the arduino team decided it was a good idea to take their beginners platform and needlessly break everything.

go though all the *.h files in the library and

replace

#include <wiring.h>

with

#include <Arduino.h>

or copy Arduino.h into a file called wiring.h it should start working

That worked! Also copied the library folders from the Arduino app to the "libraries" folder.
