Recent versions of apib require libev now, which is popular enough dependency and should be provided by your distribution as a package (header files might be provided by the corresponding -dev or -devel package). Do you have that installed?

If your distribution installs files under custom prefix, e.g. /usr/local, you'd also need to tell the compiler where to look for those headers and libraries.
