Pierre,
this is probably a problem related to graphics output, not octave as 
such.

On Mac OS X you can use octave with or without XWindows.
Fink does not require you to have XWindows to install octave, but it 
does require gnuplot.

So, if you have XWindows check the value of env variable DISPLAY (type 
'env' in the terminal)
and if you don't have XWindows, check the settings for gnuplot.

Make sure you have gnuplot version >3.8 which have support for AquaTerm 
(otherwise you won't have any screen output)
Check the env variable GNUTERM, it should be set to 'aqua'

More info and some modified .m files for OS X can be found at
