HOW I can install Amnesia the dark descent in Debian testing with KDE 4.4.5?

[Urkle]

those should be enought to run the GTK+ front end.. but there is a FLTK frontend which doesn't require any extra libraries (aside from stdc++).

Try doing the --target TempFolder --keep

After it fails go into TempFolder and give me the output of

ldd ./bin/linux/x86_64/libc.so.6/*


that will help in figuring out what's going on.
