Well, the best solution, may be this :
1) Log in as an unprivileged user ....
Root is for administrative tasks only,
and please use su instead of 'log in as root'.
Compiling : only the 'make install' command requires su.
2) .... Start from scratch in a new directory :
We know, this one is OK in Fedora 9 ..
It's a small package, please download it.
A lot of other libpcap versions are marked 1.0.0,
but may not work on all Linux ?
