I don't think I've ever used 'lsode', so this advice might be really  
useless :-)
But, what I'd do so to change the function you want to integrate, such  
that it contains a persistent variable that counts the number of times  
the function is evaluted. Then you can use that to print some progress  
once in a while, i.e.

function retval = myfun (varargin)
  persistent num_evals = 0;
  num_evals ++;
  if (mod (num_evals, 10))
    printf ("#");
  endif

  ## Insert your current function body here...
endfunction

I guess something like that should do the trick although I haven't tried it.
