A generous LinuxCoin user gave me SSH access to one of his boxes so I could poke around.
LinuxCoin installs the ATI SDK to /opt (which isn't a problem),
But its $LD_LIBRARY_PATH is never set. This is why LinuxCoin users can't run aticonfig commands remotely. I'm going to contact the LinuxCoin author and point this out.
For now, I advise LinuxCoin users to perform this step BEFORE running/installing smartcoin:
Temporary version (must be done after each reboot)
or
Permanent version: (you won't have to mess with it again!)
source ~/.bashrc
source ~/.bashrc
Between the recently committed code, and this... Many more installs should be working now
