Can anybody please tell me what it is that I have not right here?

On a USB HDD I have a new install Ubuntu 12.04 amd64, a new install of 12.6 drivers (amd-driver-12-6-x86_64.run) installed with the run installer. Installed CGMiner-2.7.5 from the built version. Extracted in the directory same way as I have been doing for months.
CGMiner runs as usual on BTC (a truly great piece of work)

However if I try to use scrypt for LTC I get these errors. Can somebody please tell me what that means --- in simple terms.

What is it I have screwed up?
Thanks

I'm having this same issue, except that I am using Windows 8 and the latest version of CGMiner (3.1.1, I think). I have AMD SDK 2.7 and Catalyst 13.1 drivers. I am pretty sure my .conf file is formatted correctly, and I do have settings for "thread-concurrency" : "21712,21712", and "kernel" : "scrypt" and "lookup-gap" : "2,2" in the .conf file. I am running two 7950 GPUs. I have read the scrypt readme file.

What am I doing wrong??
