pkg problems

[Terry Duell]

Hello All,
I am running Octave 3.6.3 on Fedora 17 x86_64, installed from the Fedora  
repo.
If I run the command 'pkg update', Octave complains that the 'general'  
package is required, but it is installed.
A list of installed packages returns;

octave:4> pkg list
Package Name   | Version | Installation directory
---------------+---------+-----------------------
        image *|  1.0.15 | /usr/share/octave/packages/image-1.0.15
         java *|   1.2.9 | /home/terry/octave/java-1.2.9
         lssa  |   0.1.2 | /home/terry/octave/lssa-0.1.2
miscellaneous *|   1.1.0 | /home/terry/octave/miscellaneous-1.1.0

       struct *|  1.0.10 | /home/terry/octave/struct-1.0.10

and my /home/terry/octave dir has the following;

Octave does know about these packages, as 'help pwelch' returns a story  
about that function in the signal package.

Is there something I need to do to ensure that 'pkg update' and 'pgk list'  
correctly see the packages that are installed, or is pkg broken somehow?

Cheers,
