Neeraj,

any idea why your two supposedly subsequent runs of ./configure show two different locations for pcap.h?

checking where to find pcap.h... /usr/include/pcap

versus

checking where to find pcap.h... /include

in the second run...

Looks like the development headers might be there but the library is missing. After all, have you installed libpcap?

And the simplest of all: try to install the binary rpm instead of compiling it yourself.

Good luck!

pat.
