netatalk provides a program afpstats, which uses python. The script starts with the line #!/usr/bin/env python however, there is no python executable in my system. The netatalk3 port depends on python2, but not the python meta-port. It should either run python2 (or python27) directly, or depend on the python port to get the python executable.
