Unable to find the servo library

hey guys,

i sure there simple solution can't seem find it.  hoping guys able help.

i decided change name of library had been creating , reason can't find library.

i keep getting error:

in file included servoleg2d.cpp:1:
e:\users\davey\hobby robotics\arduino-1.0\libraries\leg2d/leg2d.h:6:19: error: servo.h: no such file or directory

e:\users\davey\hobby robotics\arduino-1.0\libraries\leg2d/leg2d.h:22: error: 'servo' not name type

the arduino code trying compile located at:
arduino-1.0\myprograms\servoleg2d

code:

quote

#include <leg2d.h>

leg2d leg0;

void setup()
{
  leg0.attachservo(1,2);
  leg0.attachservo(2,3);
}

void loop()
{
  //leg0.sets1(0);
  //leg0.sets2(0);
  leg0.seteepos(130,130);
  delay(1000);
 
}

the library files located at:

arduino-1.0\libraries\leg2d\leg2d.h

does know why can't file servo library?

maybe should try re-install libraries or/and write code on new sketch.
