Yes, a Google web search definitely thinks so.

Maybe, but this thread:

http://devgurus.amd.com/thread/158568

suggests that it's an AMD vs. NVidia library conflict, so rather than
workaround it by downgrading the AMD APP SDK it might be better to
figure out the proper LD_LIBRARY_PATH settings or install these things
into non-default directories to avoid the conflict.

(I was intentionally installing into the default directories so far -
did it like a typical end user would.)
