Thanks for the quick answer!
I managed with a lot of fiddling to get it working. I believe the problems arose because I am running a 64bit linux. Indeed, if you compare our output, the only difference is in my
7 - Architecture: [ amd64 ]
7 - Architecture: [ i386 ]
As a consequence, many required libraries resided in a different folder than what the installation procedure expected: the installation said it could not find them in /usr/lib/i36-linux-gnu because they were in /usr/lib/x86_64-linux-gnu. So I renamend and relinked, then performed the installation, and afterwards undid the renaming and relinking. I don't know why this worked, so I can't recommend it, but since it worked for me, somebody might find this useful.
