Just a short update:
Like Ovidiu did, I went to libpcap-1.0.0 and my binary snort rpm doesn't 
segfault anymore. I used these:

libpcap1-debuginfo-1.0.0-6.el5.x86_64
libpcap1-1.0.0-6.el5.x86_64
libpcap1-devel-1.0.0-6.el5.x86_64

I tought 1.1.1 would be a better choice than 1.0.0 but I was obviously 
wrong..

Any comments?

They cannot scare me with their empty spaces
Between stars - on stars where no human race is
I have it in me so much nearer home
To scare myself with my own desert places.       - Robert Frost
