I have been trying to follow the instructions at http://www.nslu2-linux.org/wiki/Main/PlugComputers to install ipkg on my grey Pogoplug (Busybox 1.7).  After that I intend to install MiniDLNA, but first things first.  I have reached step 5 but when I try to run ipkg (alone or with any argument), I get a "Permission denied" error.  The root drive is writable.  I am logged in as root and the file has executable permissions.  I rebooted the Pogoplug and still no luck.  Nothing seems to be working to get ipkg to execute.  Can anyone here tell me what is wrong?

Here is an SSH session that will probably answer a lot of questions people may have when considering this:
