Hi, thanks for commenting, and sorry I lost track of this and took so
long to follow up.
This is not an rpath problem, rather it has to do with the default
run-time path used by the Octave interpreter to dynamically load
non-built-in functions from oct-files and m-files. The run-time files
themselves are distributed between the octave and octave-common
packages. However, the strings that are used to initialize the
run-time path are stored in the liboctinterp library in the liboctave1
package.
To expand on Jordi's comments above, I can see a few ways to go about
handling this.
1) Add Depends: liboctave1 (= ${source:Version}) to octave to force
the versions of octave, octave-common, and liboctave1 to be identical.
This is the quickest and easiest way to fix this without any real
drawbacks that I see.
2) Install the run-time into non-versioned directories, e.g.
/usr/share/octave/ instead of /usr/share/octave/3.6.2. This could be
done with or without upstream support. Upstream may still want to
support co-installation of multiple Octave versions that this allows.
3) Move the strings describing the default run-time path into the
octave executable. This would probably require significant surgery.
However, if liboctave1 is really intended to be a library, then it
ideally should not have knowledge of the octave interpreter or the
functions installed in the run-time path.
I vote for #1. I don't know if there's any real benefit to keeping the
liboctave1 dependency as loose as it is now.
