dbus: org.freedesktop.dbus-session.plist already exists and does not belong to a registered port

[cherryblossom.field17@…]

I'm trying to install GIMP and GAP on my MacBook Pro, which is running on OS X Yosemite, using Macports and am running into some problems. I first installed XCODE and the command line code that accompanies it. After that, I installed MacPorts. When I try to install the programs, it seems as if it's working, but then it stops whenever it gets to accessing dbus. This is what I get in Terminal when I encounter this issue:

--->  Activating dbus @1.8.16_0
Error: org.macports.activate for port dbus returned: Image error: /Library/LaunchAgents/org.freedesktop.dbus-session.plist already exists and does not belong to a registered port.  Unable to activate port dbus. Use 'port -f activate dbus' to force the activation.
Error: Failed to install dbus
Please see the log file for port dbus for details:

I also should add that this is the prompt that I use when trying to install the programs: sudo port install gimp-app gimp-gap

Your log says:

:debug:activate Image error: /Library/LaunchAgents/org.freedesktop.dbus-session.plist already exists and does not belong to a registered port.  Unable to activate port dbus. Use 'port -f activate dbus' to force the activation.

Why does that file already exist on your system?

Do you already have dbus installed outside of MacPorts? If so, remove it first.

Or did you used to have dbus installed using MacPorts, then uninstalled MacPorts following our ​uninstallation instructions? The uninstallation instructions will remove the files installed by MacPorts, if you're able to run "sudo port uninstall installed". But if you're not, and you have to resort to the brute-force removal of files at the end of those instructions, then certain files that don't follow the standard naming conventions won't be removed. The dbus launchd plist is one of those files, because its name begins with "org.freedesktop" rather than "org.macports". In this case, you can just remove the file before activating dbus, or use "sudo port -f activate dbus" to have MacPorts rename it for you.
