Hi everybody,

I'm trying to install snort 2.0.0 on RH8.0 (w/updates - kernel is 
2.4.20-13.8). I have installed libpcap 0.7.2 (compiled it; would rather not 
use rpm), and installed mysql client (in this case, using rpm).

When trying to compile snort, I can't get past the configure step. Error 
message says it cannot find libpcap, and I've tried just about everything... 
with no luck.

I've set up soft links in /usr/lib and /usr/include to libpcap files in 
/usr/local/lib and /usr/local/include, I've added /usr/local/lib to 
ld.so.conf and run ldconfig, I've used the --with-libpcap-* options in 
configure...

I'm no guru in software compiling matters, that's for sure, but I have tried 
and researched... and ran out of ideas. Any help will be appreciated!

I'm including a capture to make things clearer:
