Earlier when installing snort on a CentOS Linux server I ran into a configure error. The error related to the fact that libdnet was not located on the server and while it was installed I did not have the libdnet-devel package installed. Below is the sample output from the configure error, an expandable complete output of the configure error, and the yum command to install libdnet-devel to move past this error when installing snort.

To resolve the above error you need to install libdnet-devel using yum on CentOS Linux or something like apt-get on Ubuntu Linux.
Install libdnet-devel On CentOS Linux:
- [root@dev ~]# yum -y install libdnet-devel

You should now be able to move past the snort configure error and proceed to compiling snort on CentOS Linux.
