You shouldn't run fsck on _some_ platforms on an inode fileserver  
partition.
I assume you don't have one of those since it's a lot of pain if  
possible at all to actually be able to run an inode fileserver on  
Linux (I don't know anybody doing that on Linux), it's not related to  
your problem.

AFS has nothing to do with your vanished libs. I'm pretty sure of that.

The other remarkable thing I saw was:
Your cache is on an ext3 filesystem, which is not supposed to be that  
way, and can cause trouble.
