[mrtg] cfgmaker failing

I'm having problems getting cfgmaker to read a linux box. This is running on a CentOS box as a yum installed binary.
I do have this system already reading data from a Cisco switch, so I suspect the binaries are working fine.

Any ideas would be appreciated.

The error looks like snmp is the issue:

[root at tuxnldds01 tuxnldds01]# cfgmaker --global 'WorkDir: /var/www/html/tuxnldds01/' --global 'Options[_]: bits,growright' -output ./tuxnldds01.cfg

However snmpwalk against that mib seems to work just fine:

I have a very simple snmp.cfg:
[root at tuxnldds01 tuxnldds01]# more /etc/snmp/snmpd.conf
rocommunity  public
syslocation  "Tucson DataCenter"
syscontact  nccops at vaisala.com

SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux
