Rebuild Problem

[beno -]

Hi;
I upgraded my box  on the other side of the planet and things went pretty well. I can ssh in and the Web sites serve. However, qmail is down and I tried to nmap and both gave me the same errors from having deleted the old libraries (as someone suggested I do). Here are at least some of the libraries I need to rebuild:

libpcap.so.3
ld-elf.so.1
libc.so.5

How do I do this?
TIA,
beno3
