I always wondered howto create debian packages and always needed psi deb packages, so I just tried to create one package for psi. Two things done by one research 
.
And a step further; create a script which does the job for me. Just give it the source and the destination and it will bring me a psi deb package to my desktop.
For all who want to do this too, here is my script: mkpsideb.tar.gz
The usage is easy, as I said, the source directory and then the configure prefix directory and you are done. If some additional configure options are needed to compile psi on your desk, the third parameter is a direct passthrough to configure.
Example:
psi source is at ~/Desktop/psi-0.13
Script is placed at the Desktop.
so open up a terminal and do the following steps:
cd ~/Desktop
./mkpsideb.sh psi-0.13 /opt/psi-dev/0.13
And then you have a psi debian package right at your desktop.
But please, have a look into the Script before! You should min. change the maintainer setting at the very top variables.
Prerequisite is, that you can at least build psi manually.
