R devel - Aug 2014 - parallel::detectCores(TRUE) gives: Error in system(cmd, TRUE) : error in running command

Hi,

Both under the current R-devel (r66456) and a version from about 3
months ago, I experience the following behavior:
> parallel::detectCores(TRUE)
Error in system(cmd, TRUE) : error in running command
> traceback()
3: system(cmd, TRUE)
2: gsub("^ +", "", system(cmd, TRUE)[1])
1: parallel::detectCores(TRUE)
>
This is on Ubuntu 14.04. Does anybody else see this? [I currently have
quite a heavy workload, otherwise I would have installed and tested it
also under 3.1.1]

Cheers,

Marius

Same under R 3.1.1

Error in system(cmd, TRUE) : error in running command

Best,
Tobias

The same is true in R-2.14.1 on  Ubuntu 12.04.4 LTS .  Put a trace on
system with
  trace(system, quote(print(command)))
  parallel::detectCores(TRUE)
and you will see the offending shell command.
