ldd

[Sidney Brooks <sidneybrooks@vtc.net>]

I gave more hard disk space to Debian and therefore had to reinstall it. 
When I reinstalled two programs that worked before, I got library error 
messages. I then ran ldd and got:
    a.out or ELF
What does this mean and what do I do about it?
I ran ldd on programs that do work and got the usual output.
