The packages are probably installed OK, but may not be loaded into Octave.
run "pkg list" to see which packages are installed and which loaded.
Packages with an * are loaded.
This what it says on my system...

octave:1> pkg list
Package Name    | Version | Installation directory
----------------+---------+-----------------------
 combinatorics  |   2.0.0 | /home/terry/octave/combinatorics-2.0.0
       control *|   2.4.2 | /home/terry/octave/control-2.4.2
data-smoothing *|   1.3.0 | /home/terry/octave/data-smoothing-1.3.0
       general *|   1.3.2 | /home/terry/octave/general-1.3.2
       gnuplot *|   1.0.1 | /home/terry/octave/gnuplot-1.0.1
         image *|   2.0.0 | /home/terry/octave/image-2.0.0
            io *|   1.2.1 | /home/terry/octave/io-1.2.1
          java *|   1.2.9 | /home/terry/octave/java-1.2.9
linear-algebra *|   2.2.0 | /home/terry/octave/linear-algebra-2.2.0
 miscellaneous *|   1.2.0 | /home/terry/octave/miscellaneous-1.2.0
        odepkg *|   0.8.4 | /home/terry/octave/odepkg-0.8.4
         optim *|   1.2.2 | /home/terry/octave/optim-1.2.2
          plot *|   1.1.0 | /home/terry/octave/plot-1.1.0
        signal *|   1.2.1 | /home/terry/octave/signal-1.2.1
       specfun *|   1.1.0 | /home/terry/octave/specfun-1.1.0
    statistics *|   1.2.0 | /home/terry/octave/statistics-1.2.0
        struct *|  1.0.10 | /home/terry/octave/struct-1.0.10

To ensure that they all load each time I run Octave I have edited my  
.octaverc file (linux), which now looks like this...

## Begin savepath auto-created section, do not edit
  addpath ('/home/terry/Myoctave:/home/terry/octave');
## End savepath auto-created section
## pkg load combinatorics
pkg load control
pkg load general
pkg load gnuplot
pkg load image
pkg load io
pkg load java
pkg load linear-algebra
pkg load miscellaneous
pkg load odepkg
pkg load optim
pkg load plot
pkg load signal
pkg load specfun
pkg load statistics
pkg load struct
pkg load data-smoothing

See if any of this helps.

Cheers,
