Hi there C/CPP Experts,
im struggeling with strange none-intuitive error messages in the arduino 1.01 IDE when using my experimental libraries for buttons and leds.
Here is the list of error messages the compiler complains about:

i once made a led and a button library (cpp + h files) within the sketch folder using #include "Led.h" #include "Button.h" to import them.
they worked just fine.
yesterday to save my work i copied those two libraries to the Arduino 1.01 Library folder. each in seperate subdir with the exact same foldername as the class name.
even though i wanted to keep on using my "local libs" (local to the adruino sketchs folder) i was NOT changing the includes into something like #include and stuck with the #include "mylib.h"
However.. things started to get strange here. even though i would expect the compiler from still using my local lib files, it somehow sees/uses those libs in the library/ folder of the arduino ide and now complains about multiple definitions.
Then things gets even worse when i try to rename those libs and folders in the arduinos library directory to avoid collisions. but it sucks.
The Problem seems to go away if i remove my libs from the Arduino/library folders again and just have it with my arduino sketch code in the same folder.
Should not there be a way to have multiple versions ob my libraries laying around and exclusively import/include a single specific one without colliding somewhere somehow ?!?
Anything i should do better?
thanks in advance for any useful advice.
Here is my example Button.h
