calls fail with "undefined symbol"

Hi,

after installing octave-symbolic via synaptic calls to functions in symbols.oct fail with

  "error: /usr/lib/octave/packages/symbolic-1.0.6/x86_64-pc-linux-gnu-api-v32/symbols.oct: undefined symbol: _ZNK5GiNaC5basic5evalfEi"

the symbol being

  GiNaC::basic::evalf(int) const

This seems to be some missing static dependence, symbols.oct shows no unsatisfied dependencies:

I'm running Ubuntu 8.10 on a Core2 Duo. The packages version numbers are

octave3.0: 1:3.0.1-6ubuntu1
octave-symbolic: 1.0.6-1
(In case it matters---octave-symbolic doesn't list these as dependencies---
libginac1.4 + libginac-dev: 1.4.3-1
libcln5 + libcln-dev: 1.2.2-2)

Downloading the current version of the symbolic package (1.0.7) from http://octave.sourceforge.net/symbolic/ and compiling solves the problem.
Is this a bug? Or am I missing something?

Cheers,
Christian
