Yes, a Google web search definitely thinks so.

Maybe, but this thread:

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.)
