Installation fails (error)

Hey guys!

First I have to say that I'm german, so my English is not very good.
I hope you'll understand me ;)

This is my problem:

Today I tried to install SpaceBukkit on my Debian server.
I downloaded the script (install.sh) and started it.
I already got mySQL and this stuff...

But suddenly there came an error, here it is:

Downloading Spacebukkit now...install.sh: 452: i: not found
install.sh: 452: i: not found
install.sh: 452: i: not found

install.sh: 452: i: not found
install.sh: 452: i: not found

I don't know what's the meaning of it but my SpaceBukkit is not working.
I wanted to install it on "/home/minecraft/SpaceBukkit" .
I hope someone can help me.

Thanks :)
