No RAID configuration found (dmraid)

Hi,

I have problems to check my raid with dmraid. dmraid is installed and accessible:

$ ls -ld /sbin/
drwxr-xr-x 2 root root 4096 Jan  5 16:10 /sbin/
$ ls -l /sbin/dmraid
-rwxr-xr-x 1 root root 21168 Feb 18  2014 /sbin/dmraid

$ /sbin/dmraid -r
/dev/sdb: ddf1, ".ddf1_disks", GROUP, ok, 1953253376 sectors, data@ 0
/dev/sda: ddf1, ".ddf1_disks", GROUP, ok, 1953253376 sectors, data@ 0

$ dmraid -s
**\* Group superset .ddf1_disks
--> Active Subset
name   : ddf1_all
size   : 1953253376
stride : 128
type   : mirror
status : ok
subsets: 0
devs   : 2
spares : 0

but not with this script:

$ ./check_raid.pl -p dmraid -d
check_raid Version 3.2.4
See CONTRIBUTING.md how to report bugs with debug data:

No RAID configuration found (tried: dmraid)

I found out, that the script is returning 0 at line 4748:

  return 0 unless -e $this->{commands}{dmraid}[1];

The script was tested as root - this can't be a sudo or file permission problem.

Thank you for having a look.
