Ticket #563 - DSCreate.pm: Error messages cannot be used in the if expression since they could be localized.
Bug description: Error messages from the command line interface
could be localized based upon the users' configuration. But the
script expects English sentence.
Fix description: Set the C locale '$ENV{LANG} = "C"' before running
the command line if the message from the command is examined in
the expression.
