You should be using ${filespath}, not ${filesdir}. The former is the absolute path, the latter is the path relative to the port directory.

Using ${filesdir} coincidentally worked because I guess the working directory happened to be derby's port directory, and adding the new dependency seems to cause MacPorts internally to change its working directory during the processing of that dependency. Ports shouldn't rely on the current working directory being anything in particular and should use variables representing absolute paths.
