Dear Glynn,

The problem seems to be in the "do_zoom" module here's the output:

maybe it's a debian specific problem?

Then nviz failed to compile for some reason. You will need to examine
the output from "make" in order to determine the reason.

["nviz" itself is a script but, if the NVWISH2.2 executable fails to
compile, make will abort processing the visualization/nviz directory
without installing the nviz script.]

Right; this corresponds to a recent change.

No; AFAIK, it applies to anything using Mesa 3.x. The library defines
glXCreatePbuffer, so configure defines HAVE_PBUFFERS, so do_zoom.c
tries to use pbuffers, which fails because GLX_PBUFFER_WIDTH/HEIGHT
aren't defined in the header file.

For now, the simplest solution is to remove the line:

  #define HAVE_PBUFFERS 1

from src/include/config.h.
