PokerTH 0.6 on Debian Lenny AMD64(testing; x86_64)

I downloaded the installer and try to run it but I got the following error:

cd ~/PokerTH-0.6-beta
./pokerth.sh

/home/gvm/PokerTH-0.6-beta/./pokerth: error while loading shared libraries: libmikmod.so.2: cannot open shared object file: No such file or directory

Because of my problem with skype I thought that this is maybe the same problem.
So I copied the script and only changed the first line from:

lib=`skype 2>&1 | awk '{print $7}' | cut -d':' -f1`

to

lib=`./pokerth.sh 2>&1 | awk '{print $7}' | cut -d':' -f1`

For the full script: see my post about Skype
