Error & warnings in installing Libnet-1.1.x & Libnet-config not found error.
 

I am doing virtual router project in Red Hat Linux Kernel-2.6
I installed the libnet-1.1.x library from packetfactory.net site and tried to installed using the "./configure, make, make install " sequence and received the following,

---------------------------------
Ther seems to be problem with the installation and compiling the sample programs by make, make install.

After this installation , I used ** gcc -Wall `libnet-config --defines` libnet-example-x.c -o libnet-example-x `libnet-config --libs` ** for compiling the sample packet injection programs from packetfactory.net and I got
Error: libnet-config not found - two times.
