IIRC this means you have either libev but the libevent headers installed
or the other way around, not sure anymore. Please check which of the
libev* packages you have installed.
root@debian:~/dect/libdect# dpkg --get-selections | grep libev libev-dev install libev3 install libevent-1.4-2 install libevent-core-1.4-2 install libevent-dev install libevent-extra-1.4-2 install root@debian:~/dect/libdect#
Fixed by install libev-libevent-dev package
