Are you sure that the location of sbin is in your path. It usually is, 
but just to be on the safe side, try specifying the path to ldconfig as 
well.

In my chase that is:
$ which ldconfig
   /sbin/ldconfig
$/sbin/ldconfig

Otherwise it may be sudo that is not recognized, then try:

$su root
PASSWORD FOR ROOT-USER
$which ldconfig
   /sbin/ldconfig
$/sbin/ldconfig

Hope this helps.
