From the readme file

You may "make test" to test the system. It will attempt to open a connection to a database at beta.crbm.cnrs-mop.fr:20000100. You may change these defaults by setting the environment variables ACEDB_HOST and ACEDB_PORT, or by defining them on the command line, as in: make test ACEDB_HOST=localhost ACEDB_PORT=200005 However, since some of the tests are dependent on specific values in the database, this may cause some tests to fail. Do not be alarmed if a handful of tests fail. Do be alarmed if all of the tests fail.

It connects to the getaceserver, so you need it up and running, before running the tests. Take a look at t/basic.t and you'll see that it wants to open a socket th the Aceserver and port.
