problem with rosws merge
when I run "roslocate info ROSARIA | rosws merge -" in order to install ROSARIA, happens an error:
basilio@lcarobo:~/fuerte_workspace$ roslocate info ROSARIA | rosws merge -
Traceback (most recent call last):
File "/usr/local/bin/rosws", line 64, in <module>
sys.exit(rosinstall.rosws_cli.rosws_main(sys.argv))
File "/usr/local/lib/python2.7/dist-packages/rosinstall/rosws_cli.py", line 440, in rosws_main
return ws_commands[command](workspace, args)

pipedata = "".join(sys.stdin.readlines())
NameError: global name 'sys' is not defined
close failed in file object destructor:
sys.excepthook is missing
lost sys.stderr
how can I fix it? is there any package missing?
