Looks like a missing dependency. rrdtool 1.2.x depends on libart_lgpl
(as well as libfreetype and libpng). The first thing to try is ldd
(or the equivalent on OpenBSD). Here is the output on my Fedora Core
6 box:
$ ldd `which rrdtool`
linux-gate.so.1 => (0x00ddf000)
librrd.so.2 => /usr/lib/librrd.so.2 (0x00212000)
libpng12.so.0 => /usr/lib/libpng12.so.0 (0x05f1f000)
libz.so.1 => /usr/lib/libz.so.1 (0x00d4b000)
libart_lgpl_2.so.2 => /usr/lib/libart_lgpl_2.so.2 (0x006ea000)
libm.so.6 => /lib/libm.so.6 (0x00d03000)
libc.so.6 => /lib/libc.so.6 (0x00bc4000)
libfreetype.so.6 => /usr/lib/libfreetype.so.6 (0x05e9d000)
/lib/ld-linux.so.2 (0x001f5000)

Try running the equivalent rrdtool graph command at the command-line
(this may not be perfect, but it's close):
rrdtool graph
/var/www/htdocs/test/test.png
--start -900
--end -300
DEF:test=$rrd_root/$host/$host_cpu.rrd:ds0:AVERAGE
DEF:test2=$rrd_root/$host/$host_cpu.rrd:ds1:AVERAGE
PRINT:test:AVERAGE:%lf
PRINT:test2:AVERAGE:%lf

If that shows the same error message, the problem lies with rrdtool, not RRDs.
