The `x11-toolkits/gtkmm24' port installs docs in /usr/X11R6/share/devhelp/books, as the `x11-toolkits/gtk--2' do. At deinstall time, it tries to remove the `devhelp' directory, but if gtk--2 is installed too, it prints a warning. gtk--2 doesn't try to remove it.
State Changed From-To: open->closed Thanks for the report, but a different solution was used.
