When i run which gcc and which g++, it returned /usr/bin/gcc and
/usr/bin/g++ respectively 

concerning issuing pkg install -forge
communications within Octave session, it returned the following errors:


error: the following dependencies where unsatisfied:
 communications
needs signal >= 1.0.0
 communications needs image >=
0.0.0
octave-3.4.0:1> pkg install -forge signal
error: the following
dependencies where unsatisfied:
 signal needs optim >= 1.0.0
 signal
needs specfun >= 0.0.0
 signal needs control >= 2.2.3

I have downloaded
these packages but would like to hear from you first.

thanks

James
