Because they are compiled functions and are in the file gf.cc ... How 
did you get your version of Octave? Does the distribution you are using 
supply the communication package already (check the command "pkg list"). 
If not, why not just install the octave-forge communications package 
with the pkg function and let Octave itself deal with ensuring that 
these functions are installed correctly?
