Comment(by fbissey):

 Replying to [comment:6 kcrisman]:
 > Interestingly, it now includes Qhull for triangulations.  This is an
 optional Sage package, but maybe after this upgrade we wouldn't need it as
 that any more?  (Of course, version rot could be a problem.)

 I have looked a little bit more in depth at that. I noticed that in Gentoo
 scipy-0.9.0 now pulls qhull as a dependency. If there a version of
 libqhull.{so,a} on the system it will be used rather than the internally
 built static library. Said static library is not installed by scipy just
 rolled up in their created module.

 In summary this version of scipy includes libqhull functionality (as far
 as scipy uses it at least) but doesn't provide the qhull library or any of
 the executables built by qhull normally.

 Depending on what you want to do I think that means you don't want to
 remove qhull from the optional spkg unless you want to force access to its
 functionality through the scipy interface.

 For info it also bundles superLU from experimental in the same way.
