Im following the guide here: https://help.ubuntu.com/community/Leafnode2. On my Ubuntu 10.10 Server VPS (its what they had, I know its not LTS or anything but if you could just help me out here that would be great) and when i perform the following script:

mkdir -pv $HOME/leafnode_build && cd $HOME/leafnode_build && \
wget http://home.pages.de/~mandree/leafnode/beta/leafnode-2.0.0.alpha20110807a.tar.bz2 && \
tar xjvf leafnode-2.0.0.alpha20110807a.tar.bz2 && cd leafnode-2.0.0.alpha20110807a && \
./configure --prefix=/usr \
--sysconfdir=/etc/leafnode \
--mandir=/usr/man \
--localstatedir=/var \
--enable-runas-user=news \
--enable-spooldir=/var/spool/news && \
make && \
sudo checkinstall -D --install=yes --fstrans=no --pakdir $HOME/leafnode_build \
   --pkgname leafnode --backup=no --deldoc=yes --deldesc=yes --delspec=yes \ 
   --default --pkgversion "2.0.0.alpha20110807a"

I get this error:

========================= Installation results ===========================
/var/tmp/tmp.ZquOW7XgSU/installscript.sh: 4:  : not found

****  Installation failed. Aborting package creation.

Cleaning up...OK

Bye.


Thanks in advance
