Problem with PS2 libraries

Projects Programming
1

With every PS2 library I try, other than PS2Keyboard library,I always get an error like this saying:

C:\Users\regor2\Documents\Arduino\libraries\ps2/ps2.h:11:22: error: WProgram.h: No such file or directory

This one is the ps2 library (the ps2_mouse example)

The library location looks like this: C:/Users/regor2/Documents/Arduino/libraries/ps2/ Which, with my understanding is the way it should look by what it said at arduino.cc!
Just to make sure, I then installed the Time library which does work!
I am running Windows 7.
Any suggestions on what to try next?

The library sounds like it is an old version.
Change the references to WProgram.h in the library files to Arduino.h
