     I just re-checked the current workman port (workman-1.3.tgz in
packages-current) to verify nothing's changed:

    > ls -l /usr/X11R6/bin/workman 
    -rwxr-xr-x  1 root  wheel  98304 Dec 18 15:14 /usr/X11R6/bin/workman*

    > strings /usr/X11R6/bin/workman | grep ^/dev
    /dev/rcd0c

    > workman
    Warning: /var/run/workman.pid: Permission denied
    As root, please run

    chmod 666 /dev/rcd0c

    to give yourself permission to access the CD-ROM device.

Still SCSI-specific, not setuid root, but needs access to the CD device.

     In my workman built from the workman-atapi port:

    > strings /opt/pkg/workman/bin/workman | grep ^/dev
    /dev/rwcd0c

and I have it setuid root for that reason.
