/bin/x86_64/clc not found, The core 'OpenCL-Device 'ATI RV770'' has died unexpectedly

[GoogleCodeExporter]

What steps will reproduce the problem?
Running pyrit -r capture-file.cap -b bssid -i Dictionary-file.txt 
attack_passthrough

What is the expected output? What do you see instead?
I get this output when I runn the attack passthrough:

What version of the product are you using? On what operating system?
Ubuntu 10.04 LTS
pyrit-0.3.0

Please provide any additional information below.
This is a similar problem which I saw in two other posts, and I took the advice 
of reinstalling the ATI Stream SDK and cpyrit-opencl-0.3.0, but it didn't make 
any difference. Sample files on the SDK seem to work fine. I'm able to run 
pyrit benchmark and I get a perfectly normal output:

Running benchmark (22105.7 PMKs/s)... / 

Computed 22215.97 PMKs/s total.

I'm stumped. Thanks for any help.

so 'benchmark' works but 'attack_passthrough' kicks the error '/bin/x86_64/clc: 
not found' ? This is hard to believe as both functions use exactly the same 
code-base

any update here?

Indeed. It turns out that I was running it with sudo and that was screwing it 
up somehow. It works perfectly fine now. Thanks for helping me clear up what I 
was doing wrong.
