I am pretty new to Ubuntu Server. I have installed libevent 1.4.13 from source but I am not exactly sure where the install location is after I do make install.
Where ever the default location is for that source package...
Your best bet is to install the package from Ubuntu.
apt-get update apt-get install libevent-1.4-2 (Not sure exactly what libevent you need, but there are a few listed in packages.ubuntu.com)
