[Xymon] configure fails at RRD link

[Lynn Osburn]

Installed RRD 1.4.5 with all prereqs on HPUX 11.31
RRD examples (in /usr/local/rrdtool/share/rrdtool/examples) all worked great to verify RRD install
This being HP-UX, you'll also want to know the LD_LIBRARY_PATH
  LD_LIBRARY_PATH=/usr/local/lib:/usr/local/lib/hpux32:/usr/lib:/usr/local/rrdtool/lib
and yes, using gmake and gcc

However, when I start the xymon configure.server script, I get the following error:

Checking for RRDtool ...
test-rrd.c: In function 'main':
test-rrd.c:30: error: too few arguments to function 'rrd_graph'
gmake: *** [test-compile] Error 1
Not RRDtool 1.0.x, checking for 1.2.x
Found RRDtool include files in /usr/local/rrdtool/include
ERROR: RRDtool library files found in /usr/local/rrdtool/lib, but link fails.

The error comes from xymon-4.3.2/build/Makefile.test-rrd
test-link:
        @$(CC) $(CFLAGS) $(RRDDEF) $(RRDLIB) -o test-rrd test-rrd.o -lrrd $(PNGLIB)

Any thoughts on how to determine more specifically why the link fails?
