rrdtool (Could not save png to)

I recently installed rrdtool and I'm getting the following error when I attempt to create a .png chart:

Code:

ERROR: Could not save png to 'latency_graph.png'

What is causing rrdtool to have issues saving a graph as .png?
 
Here are the errors I got. None of them seem related to rrdtool.
Code: 
hostname# /usr/local/sbin/pkg_libchk
diablo-jdk-1.6.0.07.02_17: /usr/local/diablo-jdk1.6.0/bin/unpack200 misses libz.so.4
diablo-jdk-1.6.0.07.02_17: /usr/local/diablo-jdk1.6.0/jre/bin/unpack200 misses libz.so.4
diablo-jdk-1.6.0.07.02_17: /usr/local/diablo-jdk1.6.0/jre/lib/amd64/libzip.so misses libz.so.4
gnuplot-4.4.3: /usr/local/bin/gnuplot misses libpdf.so.8
Are you suggesting I deinstall and reinstall rrdtool? Or is there something else I should do to fix up my library issues?
 
As a side note, I thought "maybe" gnuplot could be related so I did a reinstall, but no luck. I got the same error when I ran rrdtool again to create a .png file.

Diablo is a port too and it's apparently either misconfigured or outdated. You may want to try updating java/diablo-jdk16.

P.S. Please note that initially Diablo will fail because you need to fetch some files manually. Download the files and try to build again.
