It is not our bug I think:
do_zoom.c:281: `GLX_PBUFFER_WIDTH' undeclared (first use in this function)
I have in config.h
/* define if glXCreatePbuffer exists */
#define HAVE_PBUFFERS 1
and Mesa 3.4.2. GLX_PBUFFER_WIDTH is missing (?):

That might indicate a mismatch between headers and library, although
I'm not certain. The configure test simply checks whether
glXCreatePbuffer exists in the library (checking whether a macro is
defined in a header is more work; you essentially have to compile and
link a test program).
The obvious fix is to conditionalise that code on whether
GLX_PBUFFER_{WIDTH,HEIGHT} are defined, i.e.:
#ifdef HAVE_PBUFFERS
#if defined(GLX_PBUFFER_WIDTH) && defined(GLX_PBUFFER_HEIGHT)
fprintf(stderr, "Creating PBuffer Using GLX 1.3\n");
fbc = glXChooseFBConfig(dpy, scr, 0, &elements);
if (fbc)
{
pbuf_cnt = 0;
pbuf_attrib[pbuf_cnt++] = GLX_PBUFFER_WIDTH;
pbuf_attrib[pbuf_cnt++] = width + 1;
pbuf_attrib[pbuf_cnt++] = GLX_PBUFFER_HEIGHT;
pbuf_attrib[pbuf_cnt++] = height + 1;
pbuffer = glXCreatePbuffer(dpy, fbc[0], pbuf_attrib);
if (pbuffer)
glXMakeContextCurrent(dpy, pbuffer, pbuffer, ctx_orig);
}
#endif
#endif
All of the code which references pbuffer checks that it is non-null
(even if both the headers and libraries support pbuffers, the X server
might not).
