After building with gcc 4.5, I deactivated qhull 2010.1 and activated 2011.2. 
Then I ran "make check". I encountered 13 failures related to qhull.

With gcc 4.4 and qhull 2012.2, my build ends with ...

../../run-octave -f -q -H -p . --eval "geometryimages ('voronoi', 'eps');"
error: subscript indices must be either positive integers or logicals
error: evaluating argument list element number 1

Running the tests, I see 9 failures due to qhull

Looking at the Macports port-file for qhull ...

        https://trac.macports.org/browser/trunk/dports/math/qhull/Portfile

... I see that the standard "qhull.h" is being used (not qhull.h-deprecated) by 
macports.

Rik, I don't recall which package management system you are using. Do you know 
if your qhull 2011 uses the standard qhull.h or the deprecated version?
