• Unzip the chdkptp supporting libraries:

user@scanner:~/chdkptp$ unzip cdeZq8dTGr44klacwqEsg8

• Put a wrapper script that loads the necessary libraries in /usr/bin:

user@scanner:~/chdkptp$ sudo su -
root@scanner:~# cd /usr/bin
root@scanner:/usr/bin# wget https://raw.github.com/markvdb/diybookscanner/master/misc/chdkptp
