You need to be root to use the -c flag.  Despite your prompt, I don't
think you're root.  Reproduction:

$ id
uid=1000(jdc) gid=1000(users) groups=1000(users),0(wheel)
$ pciconf -lv | wc -l
     114
$ pciconf -lc
pciconf: /dev/pci: Permission denied
$ sudo -i
box# id
uid=0(root) gid=0(wheel) groups=0(wheel),5(operator)
box# pciconf -lc | wc -l
      73
