Terry,
The function clusterSetupRNG is using the RNGstream from rlecuyer
package by default. There was a bug in the latest version of the
rlecuyer package (0.3-2). A corrected version (0.3-3) is now sitting in
the queue to be published on CRAN. So it should become available within
the next few days.
