I'm runnig freebsd, and get the following error:
Getopt::Long: unknown config parameter "auto_help" at lib/Getopt/Long.pm (autosplit into lib/auto/Getopt/Long/Configure.al) line 1009 Getopt::Long::Configure('auto_help', 'auto_version') called at /usr/local/lib/perl5/5.6.1/Getopt/Long.pm line 117 Getopt::Long::import('Getopt::Long', ':config', 'auto_help', 'auto_version') called at ./imaparchiver.pl line 23 main::BEGIN() called at /usr/local/lib/perl5/5.6.1/Getopt/Long.pm line 23 eval {...} called at /usr/local/lib/perl5/5.6.1/Getopt/Long.pm line 23 BEGIN failed--compilation aborted at ./imaparchiver.pl line 23.
What have I done wrong??
