Dear Alexander,

your suggestions worked. I could install the control and signal 
packages. thanks a lot.

moving on I tried to do the equivalent of "Hello World!" in graphics:

octave:2> x=(0:0.1:20)';
octave:3> y=sin(x);

<Error>: CGContextFillRects: invalid context 0x0. This is a serious 
error. This application, or a library it uses, is using an invalid 
context  and is thereby contributing to an overall degradation of system 
stability and reliability. This notice is a courtesy: please fix this 
problem. It will become a fatal error in an upcoming update.

This warning got repeated ~100 times and then the correct plot appeared!
