Dear pyt...@freebsd.org folks: I contribute to some open source software written in Python (http://tahoe-lafs.org ) and we rely on the standard Python metadata—which is named ".egg-info" for legacy reasons even though it doesn't have anything to do with Python Eggs—to detect whether other Python packages are installed. This works for all packages on FreeBSD since the standard Python distutils build the appropriate .egg-info files automatically and the FreeBSD packagers correctly include those files, but it doesn't work for Twisted.
That's because a few years ago the Twisted folks split Twisted into several separate packages, like "Twisted-Core", "Twisted-Web", "Twisted-Words" and so on. After a couple of released the Twisted folks decided this was more trouble than it was worth and went back to distributing a monolithic "Twisted" package, but for some reason all of the operating system distributions have continued to maintain the split-out packages. Anyway, the problem is that the py-twisted metapackage that depends on all the other split-out packages doesn't produce a "Twisted-$VERSION.egg-info" file, so therefore when our code asks "Is Twisted installed?" the answer appears to be no, since there is no "Twisted-$VERSION.egg-info" file present. Here is the issue ticket from when Debian had a similar problem which shows you how they solved it: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=477384 Here is the issue ticket from Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=523210 To fix this issue, make it so that when the py-twisted package is installed, then there exists a file named "Twisted-$TWISTEDVERSION-py$PYTHONVERSION.egg-info" on the sys.path. Thanks!
