[R-SIG-Mac] object '.lec.Random.seed.table' not found

[Hana Sevcikova]

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.
