Bug#990397: depends on deprecated qhull library

[Rafael Laboissière]

Dear PLplot developers,

I am hereby forwarding a bug report filed against the Debian plplot 
package regarding the use of a deprecated Qhull library [1]. Conversion 
of the code to the reentrant version of Qhull needs more changes than 
merely linking against libqhull_r.so instead of libqhull.so and including 
libqull_r/qhull_ra.h instead of libqull/qhull_a.h [2], and should be 
done by the upstream authors.

Best,

Rafael Laboissière
