I just encountered a problem recently and wondered whether your work 
might help it at all. The situation is uninstalling a library that 
system packages link against. The problem I hit involves 
sys-apps/shadow[USE=audit] and sys-process/audit, which I just hit on my 
own system, breaking /bin/login.

It seems like this could become part of the linkage map and thus give 
the user a warning, if it's not already -- I haven't been following this 
incredibly closely.

What do you think?

Ick, libtool libraries are the worst.
