Try "sudo apt-get install kdelibs4c2a-trinity", which should complain 
about another missing dependency, and then try to install that 
dependency etc. There is probably a better way of finding the missing 
dependency,

Several weeks ago I tried to install Ubuntu 12.04 beta 2 and Trinity 
3.5.13, but it failed. After a few minutes of "sudo apt-get install foo" 
I tracked the problem down to a missing libaudiofile0.

It looks like Ubuntu now uses (1) libaudiofile1, a symlink might have 
fixed my problem but I needed a stable system so I went back to 11.10 
and 3.5.13.

Maybe libaudiofile0 is only a problem for me :P
