| 24/10/2005
| # apt-get install octave octave-forge octave-plplot octave2.1-doc
| octave2.1-info
| # apt-get install octave2.1-headers
| 
| 15/8/2006
| Upgrade to octave 2.9:
| # apt-get install octave2.9 octave2.9-info octave2.9-doc
| octave2.9-htmldoc octave2.9-headers
| 
| Try it out, then remove octave 2.1:
| # apt-get remove --purge octave octave2.1 octave2.1-info
| octave2.1-htmldoc octave2.1-headers
| 
| Report bug #383149.

| Wonder if the problem is an interaction between octave 2.1 and 2.9
| packages.  Do a clean reinstall of octave2.9 (ie. with no octave2.1)
| 
| # apt-get remove --purge octave2.9 octave2.9-info octave2.9-doc
| octave2.9-htmldoc octave2.9-headers
| # apt-get install octave2.9 octave2.9-info octave2.9-doc
| octave2.9-htmldoc octave2.9-headers
| 
| After this fresh reinstall, symptoms are still present as before:

I'm unable to duplicate this problem.  I have an up-to-date "testing"
system and I installed Octave 2.9.7 with

  apt-get update
  apt-get -t unstable octave2.9{,-{headers,info,doc}}

and then ran

  update-alternatives --config mkoctfile
  update-alternatives --config octave
  update-alternatives --config octave-bug
  update-alternatives --config octave-config
  update-alternatives --config octave-depends

BTW, why do I have to run all these commands?  I think it would be
more friendly if running "update-alternatives --config octave" would
take care of the rest automatically so they would all stay in sync.

In any case, here is what I see:
