./Install.sh:Too many arguments: :P:UHm --long prefix:,uninstall,help,make-tar -n ./Install.sh -- on MACOS

Hi,

I downloaded BashBurn-3.1.0 from http://bashburn.dose.se/files/BashBurn-3.1.0.tar.gz. After having decompressed this archive and cd to BashBurn-3.1.0/, I ran ./Install.sh

$ ./Install.sh 
./Install.sh:Too many arguments: :P:UHm --long prefix:,uninstall,help,make-tar -n ./Install.sh --
$ echo $?
1

Can you help me ?
