Does `parallel' work for anybody? When I run

$ ls | parallel echo

I get the following error message, and nothing happens.

parallel: Warning: No more processes: Decreasing number of running jobs to =
1.
parallel: Warning: Raising ulimit -u or /etc/security/limits.conf may help.
parallel: Error: No more processes: cannot run a single job. Something is w=
rong at file-name.

Any idea about what's happening?
