If the qhull library was not installed when your copy of Octave was
compiled, then it won't magically start working just because you
install the library.  You'll need to recompile Octave from sources,
or find a version of Octave compiled for your system that is linked
with the qhull library.

3.0.2 is quite old.  Isn't there a newer package for your OS
distribution?

OK, I uninstalled and re-installed octave after installing qhull. This did not help.

I checked, and now I think, octave-3.2.4 compiled for Mandriva is
actually for Mandriva-2010, while I run Mandriva-2008, thus due to the
large generation gap in these OS-versions, the package dependencies
that I face (while trying to force install 3.2.4) is overwhelmingly
large.

My resolution is to get the OS updated once and for all, so I can
install 3.2.4 from the repos --- in the meantime, I will continue
working with the 3.2.4 that I have on another disk partition (running
PCLinuxOS) on the same machine.

Thanks for the valuable directions though ...
